Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593088, here are decompositions:

  • 41 + 31593047 = 31593088
  • 167 + 31592921 = 31593088
  • 239 + 31592849 = 31593088
  • 467 + 31592621 = 31593088
  • 521 + 31592567 = 31593088
  • 557 + 31592531 = 31593088
  • 599 + 31592489 = 31593088
  • 641 + 31592447 = 31593088

Showing the first eight; more decompositions exist.
