Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539048, here are decompositions:
- 5 + 31539043 = 31539048
- 41 + 31539007 = 31539048
- 61 + 31538987 = 31539048
- 97 + 31538951 = 31539048
- 241 + 31538807 = 31539048
- 269 + 31538779 = 31539048
- 337 + 31538711 = 31539048
- 419 + 31538629 = 31539048
Showing the first eight; more decompositions exist.
