Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531464, here are decompositions:
- 7 + 31531457 = 31531464
- 11 + 31531453 = 31531464
- 43 + 31531421 = 31531464
- 47 + 31531417 = 31531464
- 61 + 31531403 = 31531464
- 163 + 31531301 = 31531464
- 191 + 31531273 = 31531464
- 193 + 31531271 = 31531464
Showing the first eight; more decompositions exist.
