Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627218, here are decompositions:

  • 71 + 8627147 = 8627218
  • 107 + 8627111 = 8627218
  • 137 + 8627081 = 8627218
  • 167 + 8627051 = 8627218
  • 317 + 8626901 = 8627218
  • 521 + 8626697 = 8627218
  • 641 + 8626577 = 8627218
  • 701 + 8626517 = 8627218

Showing the first eight; more decompositions exist.
