Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461368, here are decompositions:
- 7 + 31461361 = 31461368
- 19 + 31461349 = 31461368
- 67 + 31461301 = 31461368
- 139 + 31461229 = 31461368
- 241 + 31461127 = 31461368
- 331 + 31461037 = 31461368
- 397 + 31460971 = 31461368
- 439 + 31460929 = 31461368
Showing the first eight; more decompositions exist.
