Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545350, here are decompositions:
- 7 + 31545343 = 31545350
- 19 + 31545331 = 31545350
- 139 + 31545211 = 31545350
- 283 + 31545067 = 31545350
- 349 + 31545001 = 31545350
- 409 + 31544941 = 31545350
- 523 + 31544827 = 31545350
- 601 + 31544749 = 31545350
Showing the first eight; more decompositions exist.
