Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665608, here are decompositions:

  • 5 + 8665603 = 8665608
  • 37 + 8665571 = 8665608
  • 41 + 8665567 = 8665608
  • 47 + 8665561 = 8665608
  • 67 + 8665541 = 8665608
  • 109 + 8665499 = 8665608
  • 137 + 8665471 = 8665608
  • 139 + 8665469 = 8665608

Showing the first eight; more decompositions exist.
