Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678736, here are decompositions:

  • 23 + 8678713 = 8678736
  • 29 + 8678707 = 8678736
  • 37 + 8678699 = 8678736
  • 43 + 8678693 = 8678736
  • 67 + 8678669 = 8678736
  • 97 + 8678639 = 8678736
  • 137 + 8678599 = 8678736
  • 149 + 8678587 = 8678736

Showing the first eight; more decompositions exist.
