Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86742, here are decompositions:

  • 13 + 86729 = 86742
  • 23 + 86719 = 86742
  • 31 + 86711 = 86742
  • 53 + 86689 = 86742
  • 113 + 86629 = 86742
  • 163 + 86579 = 86742
  • 181 + 86561 = 86742
  • 211 + 86531 = 86742

Showing the first eight; more decompositions exist.
