Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627986, here are decompositions:

  • 47 + 8627939 = 8627986
  • 83 + 8627903 = 8627986
  • 89 + 8627897 = 8627986
  • 173 + 8627813 = 8627986
  • 179 + 8627807 = 8627986
  • 293 + 8627693 = 8627986
  • 347 + 8627639 = 8627986
  • 359 + 8627627 = 8627986

Showing the first eight; more decompositions exist.
