Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637886, here are decompositions:

  • 17 + 8637869 = 8637886
  • 107 + 8637779 = 8637886
  • 137 + 8637749 = 8637886
  • 269 + 8637617 = 8637886
  • 359 + 8637527 = 8637886
  • 419 + 8637467 = 8637886
  • 563 + 8637323 = 8637886
  • 659 + 8637227 = 8637886

Showing the first eight; more decompositions exist.
