Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535460, here are decompositions:
- 31 + 31535429 = 31535460
- 37 + 31535423 = 31535460
- 41 + 31535419 = 31535460
- 43 + 31535417 = 31535460
- 79 + 31535381 = 31535460
- 83 + 31535377 = 31535460
- 139 + 31535321 = 31535460
- 149 + 31535311 = 31535460
Showing the first eight; more decompositions exist.
