Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533758, here are decompositions:

  • 37 + 31533721 = 31533758
  • 97 + 31533661 = 31533758
  • 127 + 31533631 = 31533758
  • 211 + 31533547 = 31533758
  • 241 + 31533517 = 31533758
  • 307 + 31533451 = 31533758
  • 349 + 31533409 = 31533758
  • 379 + 31533379 = 31533758

Showing the first eight; more decompositions exist.
