Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669688, here are decompositions:

  • 17 + 8669671 = 8669688
  • 19 + 8669669 = 8669688
  • 31 + 8669657 = 8669688
  • 37 + 8669651 = 8669688
  • 59 + 8669629 = 8669688
  • 61 + 8669627 = 8669688
  • 67 + 8669621 = 8669688
  • 199 + 8669489 = 8669688

Showing the first eight; more decompositions exist.
