Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678688, here are decompositions:

  • 17 + 8678671 = 8678688
  • 19 + 8678669 = 8678688
  • 89 + 8678599 = 8678688
  • 101 + 8678587 = 8678688
  • 107 + 8678581 = 8678688
  • 131 + 8678557 = 8678688
  • 181 + 8678507 = 8678688
  • 241 + 8678447 = 8678688

Showing the first eight; more decompositions exist.
