Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497470, here are decompositions:
- 3 + 31497467 = 31497470
- 7 + 31497463 = 31497470
- 61 + 31497409 = 31497470
- 79 + 31497391 = 31497470
- 157 + 31497313 = 31497470
- 241 + 31497229 = 31497470
- 283 + 31497187 = 31497470
- 313 + 31497157 = 31497470
Showing the first eight; more decompositions exist.
