Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545516, here are decompositions:
- 17 + 31545499 = 31545516
- 29 + 31545487 = 31545516
- 47 + 31545469 = 31545516
- 109 + 31545407 = 31545516
- 137 + 31545379 = 31545516
- 173 + 31545343 = 31545516
- 193 + 31545323 = 31545516
- 199 + 31545317 = 31545516
Showing the first eight; more decompositions exist.
