Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8685624, here are decompositions:

  • 5 + 8685619 = 8685624
  • 23 + 8685601 = 8685624
  • 41 + 8685583 = 8685624
  • 47 + 8685577 = 8685624
  • 53 + 8685571 = 8685624
  • 67 + 8685557 = 8685624
  • 107 + 8685517 = 8685624
  • 131 + 8685493 = 8685624

Showing the first eight; more decompositions exist.
