Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604568, here are decompositions:
- 7 + 31604561 = 31604568
- 11 + 31604557 = 31604568
- 59 + 31604509 = 31604568
- 67 + 31604501 = 31604568
- 71 + 31604497 = 31604568
- 181 + 31604387 = 31604568
- 197 + 31604371 = 31604568
- 211 + 31604357 = 31604568
Showing the first eight; more decompositions exist.
