Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627620, here are decompositions:

  • 3 + 8627617 = 8627620
  • 11 + 8627609 = 8627620
  • 17 + 8627603 = 8627620
  • 47 + 8627573 = 8627620
  • 59 + 8627561 = 8627620
  • 107 + 8627513 = 8627620
  • 173 + 8627447 = 8627620
  • 179 + 8627441 = 8627620

Showing the first eight; more decompositions exist.
