Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86790, here are decompositions:

  • 7 + 86783 = 86790
  • 19 + 86771 = 86790
  • 23 + 86767 = 86790
  • 37 + 86753 = 86790
  • 47 + 86743 = 86790
  • 61 + 86729 = 86790
  • 71 + 86719 = 86790
  • 79 + 86711 = 86790

Showing the first eight; more decompositions exist.
