Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706666, here are decompositions:

  • 19 + 8706647 = 8706666
  • 53 + 8706613 = 8706666
  • 79 + 8706587 = 8706666
  • 97 + 8706569 = 8706666
  • 109 + 8706557 = 8706666
  • 113 + 8706553 = 8706666
  • 139 + 8706527 = 8706666
  • 263 + 8706403 = 8706666

Showing the first eight; more decompositions exist.
