Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545606, here are decompositions:
- 7 + 31545599 = 31545606
- 107 + 31545499 = 31545606
- 137 + 31545469 = 31545606
- 167 + 31545439 = 31545606
- 199 + 31545407 = 31545606
- 227 + 31545379 = 31545606
- 233 + 31545373 = 31545606
- 263 + 31545343 = 31545606
Showing the first eight; more decompositions exist.
