Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604760, here are decompositions:
- 13 + 31604747 = 31604760
- 17 + 31604743 = 31604760
- 29 + 31604731 = 31604760
- 37 + 31604723 = 31604760
- 41 + 31604719 = 31604760
- 71 + 31604689 = 31604760
- 73 + 31604687 = 31604760
- 79 + 31604681 = 31604760
Showing the first eight; more decompositions exist.
