Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513264, here are decompositions:
- 5 + 31513259 = 31513264
- 71 + 31513193 = 31513264
- 173 + 31513091 = 31513264
- 191 + 31513073 = 31513264
- 227 + 31513037 = 31513264
- 257 + 31513007 = 31513264
- 317 + 31512947 = 31513264
- 647 + 31512617 = 31513264
Showing the first eight; more decompositions exist.
