Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560688, here are decompositions:
- 11 + 31560677 = 31560688
- 41 + 31560647 = 31560688
- 59 + 31560629 = 31560688
- 101 + 31560587 = 31560688
- 179 + 31560509 = 31560688
- 251 + 31560437 = 31560688
- 281 + 31560407 = 31560688
- 347 + 31560341 = 31560688
Showing the first eight; more decompositions exist.
