Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536510, here are decompositions:
- 11 + 31536499 = 31536510
- 29 + 31536481 = 31536510
- 107 + 31536403 = 31536510
- 113 + 31536397 = 31536510
- 127 + 31536383 = 31536510
- 149 + 31536361 = 31536510
- 151 + 31536359 = 31536510
- 157 + 31536353 = 31536510
Showing the first eight; more decompositions exist.
