Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712786, here are decompositions:

  • 7 + 8712779 = 8712786
  • 29 + 8712757 = 8712786
  • 37 + 8712749 = 8712786
  • 59 + 8712727 = 8712786
  • 73 + 8712713 = 8712786
  • 109 + 8712677 = 8712786
  • 157 + 8712629 = 8712786
  • 239 + 8712547 = 8712786

Showing the first eight; more decompositions exist.
