Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539028, here are decompositions:
- 41 + 31538987 = 31539028
- 239 + 31538789 = 31539028
- 317 + 31538711 = 31539028
- 449 + 31538579 = 31539028
- 467 + 31538561 = 31539028
- 617 + 31538411 = 31539028
- 701 + 31538327 = 31539028
- 821 + 31538207 = 31539028
Showing the first eight; more decompositions exist.
