Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545384, here are decompositions:
- 5 + 31545379 = 31545384
- 11 + 31545373 = 31545384
- 41 + 31545343 = 31545384
- 53 + 31545331 = 31545384
- 61 + 31545323 = 31545384
- 67 + 31545317 = 31545384
- 97 + 31545287 = 31545384
- 151 + 31545233 = 31545384
Showing the first eight; more decompositions exist.
