Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539624, here are decompositions:
- 31 + 31539593 = 31539624
- 37 + 31539587 = 31539624
- 41 + 31539583 = 31539624
- 101 + 31539523 = 31539624
- 157 + 31539467 = 31539624
- 211 + 31539413 = 31539624
- 223 + 31539401 = 31539624
- 257 + 31539367 = 31539624
Showing the first eight; more decompositions exist.
