Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627866, here are decompositions:

  • 53 + 8627813 = 8627866
  • 59 + 8627807 = 8627866
  • 89 + 8627777 = 8627866
  • 167 + 8627699 = 8627866
  • 173 + 8627693 = 8627866
  • 227 + 8627639 = 8627866
  • 239 + 8627627 = 8627866
  • 257 + 8627609 = 8627866

Showing the first eight; more decompositions exist.
