Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618744, here are decompositions:

  • 41 + 31618703 = 31618744
  • 107 + 31618637 = 31618744
  • 197 + 31618547 = 31618744
  • 281 + 31618463 = 31618744
  • 383 + 31618361 = 31618744
  • 557 + 31618187 = 31618744
  • 617 + 31618127 = 31618744
  • 683 + 31618061 = 31618744

Showing the first eight; more decompositions exist.
