Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497568, here are decompositions:
- 17 + 31497551 = 31497568
- 41 + 31497527 = 31497568
- 101 + 31497467 = 31497568
- 107 + 31497461 = 31497568
- 227 + 31497341 = 31497568
- 269 + 31497299 = 31497568
- 281 + 31497287 = 31497568
- 317 + 31497251 = 31497568
Showing the first eight; more decompositions exist.
