Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539004, here are decompositions:
- 17 + 31538987 = 31539004
- 53 + 31538951 = 31539004
- 197 + 31538807 = 31539004
- 251 + 31538753 = 31539004
- 293 + 31538711 = 31539004
- 311 + 31538693 = 31539004
- 443 + 31538561 = 31539004
- 593 + 31538411 = 31539004
Showing the first eight; more decompositions exist.
