Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539444, here are decompositions:
- 5 + 31539439 = 31539444
- 23 + 31539421 = 31539444
- 31 + 31539413 = 31539444
- 43 + 31539401 = 31539444
- 67 + 31539377 = 31539444
- 107 + 31539337 = 31539444
- 113 + 31539331 = 31539444
- 173 + 31539271 = 31539444
Showing the first eight; more decompositions exist.
