Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712886, here are decompositions:

  • 23 + 8712863 = 8712886
  • 59 + 8712827 = 8712886
  • 107 + 8712779 = 8712886
  • 137 + 8712749 = 8712886
  • 173 + 8712713 = 8712886
  • 257 + 8712629 = 8712886
  • 353 + 8712533 = 8712886
  • 389 + 8712497 = 8712886

Showing the first eight; more decompositions exist.
