Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604738, here are decompositions:
- 7 + 31604731 = 31604738
- 19 + 31604719 = 31604738
- 97 + 31604641 = 31604738
- 127 + 31604611 = 31604738
- 181 + 31604557 = 31604738
- 229 + 31604509 = 31604738
- 241 + 31604497 = 31604738
- 367 + 31604371 = 31604738
Showing the first eight; more decompositions exist.
