Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601690, here are decompositions:

  • 7 + 8601683 = 8601690
  • 23 + 8601667 = 8601690
  • 37 + 8601653 = 8601690
  • 43 + 8601647 = 8601690
  • 59 + 8601631 = 8601690
  • 61 + 8601629 = 8601690
  • 103 + 8601587 = 8601690
  • 109 + 8601581 = 8601690

Showing the first eight; more decompositions exist.
