Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691684, here are decompositions:

  • 11 + 8691673 = 8691684
  • 17 + 8691667 = 8691684
  • 31 + 8691653 = 8691684
  • 41 + 8691643 = 8691684
  • 61 + 8691623 = 8691684
  • 97 + 8691587 = 8691684
  • 101 + 8691583 = 8691684
  • 103 + 8691581 = 8691684

Showing the first eight; more decompositions exist.
