Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689646, here are decompositions:

  • 3 + 8689643 = 8689646
  • 19 + 8689627 = 8689646
  • 37 + 8689609 = 8689646
  • 73 + 8689573 = 8689646
  • 103 + 8689543 = 8689646
  • 109 + 8689537 = 8689646
  • 157 + 8689489 = 8689646
  • 193 + 8689453 = 8689646

Showing the first eight; more decompositions exist.
