Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596290, here are decompositions:
- 97 + 31596193 = 31596290
- 127 + 31596163 = 31596290
- 139 + 31596151 = 31596290
- 163 + 31596127 = 31596290
- 223 + 31596067 = 31596290
- 241 + 31596049 = 31596290
- 283 + 31596007 = 31596290
- 307 + 31595983 = 31596290
Showing the first eight; more decompositions exist.
