Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539504, here are decompositions:
- 5 + 31539499 = 31539504
- 37 + 31539467 = 31539504
- 83 + 31539421 = 31539504
- 103 + 31539401 = 31539504
- 127 + 31539377 = 31539504
- 137 + 31539367 = 31539504
- 151 + 31539353 = 31539504
- 167 + 31539337 = 31539504
Showing the first eight; more decompositions exist.
