Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604436, here are decompositions:
- 53 + 31604383 = 31604436
- 79 + 31604357 = 31604436
- 89 + 31604347 = 31604436
- 137 + 31604299 = 31604436
- 139 + 31604297 = 31604436
- 173 + 31604263 = 31604436
- 307 + 31604129 = 31604436
- 337 + 31604099 = 31604436
Showing the first eight; more decompositions exist.
