Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678642, here are decompositions:

  • 3 + 8678639 = 8678642
  • 43 + 8678599 = 8678642
  • 61 + 8678581 = 8678642
  • 283 + 8678359 = 8678642
  • 331 + 8678311 = 8678642
  • 439 + 8678203 = 8678642
  • 463 + 8678179 = 8678642
  • 613 + 8678029 = 8678642

Showing the first eight; more decompositions exist.
