Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678646, here are decompositions:

  • 7 + 8678639 = 8678646
  • 43 + 8678603 = 8678646
  • 47 + 8678599 = 8678646
  • 59 + 8678587 = 8678646
  • 89 + 8678557 = 8678646
  • 127 + 8678519 = 8678646
  • 139 + 8678507 = 8678646
  • 173 + 8678473 = 8678646

Showing the first eight; more decompositions exist.
