Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604146, here are decompositions:
- 17 + 31604129 = 31604146
- 47 + 31604099 = 31604146
- 89 + 31604057 = 31604146
- 113 + 31604033 = 31604146
- 227 + 31603919 = 31604146
- 257 + 31603889 = 31604146
- 269 + 31603877 = 31604146
- 317 + 31603829 = 31604146
Showing the first eight; more decompositions exist.
