Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656960, here are decompositions:

  • 41 + 8656919 = 8656960
  • 89 + 8656871 = 8656960
  • 113 + 8656847 = 8656960
  • 131 + 8656829 = 8656960
  • 173 + 8656787 = 8656960
  • 227 + 8656733 = 8656960
  • 233 + 8656727 = 8656960
  • 239 + 8656721 = 8656960

Showing the first eight; more decompositions exist.
