Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574906, here are decompositions:

  • 19 + 31574887 = 31574906
  • 43 + 31574863 = 31574906
  • 127 + 31574779 = 31574906
  • 229 + 31574677 = 31574906
  • 409 + 31574497 = 31574906
  • 439 + 31574467 = 31574906
  • 457 + 31574449 = 31574906
  • 463 + 31574443 = 31574906

Showing the first eight; more decompositions exist.
