Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467992, here are decompositions:
- 43 + 31467949 = 31467992
- 139 + 31467853 = 31467992
- 163 + 31467829 = 31467992
- 181 + 31467811 = 31467992
- 229 + 31467763 = 31467992
- 271 + 31467721 = 31467992
- 421 + 31467571 = 31467992
- 433 + 31467559 = 31467992
Showing the first eight; more decompositions exist.
