Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640762, here are decompositions:

  • 23 + 8640739 = 8640762
  • 29 + 8640733 = 8640762
  • 43 + 8640719 = 8640762
  • 59 + 8640703 = 8640762
  • 61 + 8640701 = 8640762
  • 71 + 8640691 = 8640762
  • 73 + 8640689 = 8640762
  • 79 + 8640683 = 8640762

Showing the first eight; more decompositions exist.
