Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497008, here are decompositions:
- 7 + 31497001 = 31497008
- 19 + 31496989 = 31497008
- 31 + 31496977 = 31497008
- 61 + 31496947 = 31497008
- 181 + 31496827 = 31497008
- 199 + 31496809 = 31497008
- 229 + 31496779 = 31497008
- 331 + 31496677 = 31497008
Showing the first eight; more decompositions exist.
