Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627878, here are decompositions:

  • 11 + 8627867 = 8627878
  • 71 + 8627807 = 8627878
  • 101 + 8627777 = 8627878
  • 137 + 8627741 = 8627878
  • 179 + 8627699 = 8627878
  • 197 + 8627681 = 8627878
  • 239 + 8627639 = 8627878
  • 251 + 8627627 = 8627878

Showing the first eight; more decompositions exist.
