Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604746, here are decompositions:
- 3 + 31604743 = 31604746
- 23 + 31604723 = 31604746
- 59 + 31604687 = 31604746
- 137 + 31604609 = 31604746
- 293 + 31604453 = 31604746
- 359 + 31604387 = 31604746
- 389 + 31604357 = 31604746
- 443 + 31604303 = 31604746
Showing the first eight; more decompositions exist.
