Welcome to 2017, a prime year!

When was the last prime year?

When will be the next prime year?

Also... 9² + 44² = 2017

I'll vote for a "lastprime" function in the WP34s if you are going to ask more questions like that

The code is in XROM, just not included in any image:


It would be easy enough to key this in as a user program.

Happy New Year to everyone.

A few funny things about 2017:

2017 = 9^2+44^2
= 12^2+28^2+33^2
= 7^3+7^3+11^3
= 6^3+7^3+9^3+9^3
= 2^3+4^3+6^3+9^3+10^3
= 1^3+6^3+6^3+7^3+8^3+9^3 = ....

Best wishes,
JM.
