Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604238, here are decompositions:
- 11 + 31604227 = 31604238
- 19 + 31604219 = 31604238
- 47 + 31604191 = 31604238
- 101 + 31604137 = 31604238
- 109 + 31604129 = 31604238
- 139 + 31604099 = 31604238
- 181 + 31604057 = 31604238
- 251 + 31603987 = 31604238
Showing the first eight; more decompositions exist.
