Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604904, here are decompositions:
- 41 + 31604863 = 31604904
- 101 + 31604803 = 31604904
- 137 + 31604767 = 31604904
- 157 + 31604747 = 31604904
- 173 + 31604731 = 31604904
- 181 + 31604723 = 31604904
- 223 + 31604681 = 31604904
- 257 + 31604647 = 31604904
Showing the first eight; more decompositions exist.
