Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545612, here are decompositions:
- 5 + 31545607 = 31545612
- 13 + 31545599 = 31545612
- 113 + 31545499 = 31545612
- 173 + 31545439 = 31545612
- 211 + 31545401 = 31545612
- 233 + 31545379 = 31545612
- 239 + 31545373 = 31545612
- 269 + 31545343 = 31545612
Showing the first eight; more decompositions exist.
