Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660628, here are decompositions:

  • 5 + 8660623 = 8660628
  • 17 + 8660611 = 8660628
  • 19 + 8660609 = 8660628
  • 59 + 8660569 = 8660628
  • 89 + 8660539 = 8660628
  • 101 + 8660527 = 8660628
  • 167 + 8660461 = 8660628
  • 191 + 8660437 = 8660628

Showing the first eight; more decompositions exist.
