Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539454, here are decompositions:

  • 41 + 31539413 = 31539454
  • 53 + 31539401 = 31539454
  • 101 + 31539353 = 31539454
  • 263 + 31539191 = 31539454
  • 311 + 31539143 = 31539454
  • 467 + 31538987 = 31539454
  • 503 + 31538951 = 31539454
  • 647 + 31538807 = 31539454

Showing the first eight; more decompositions exist.
