Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758666, here are decompositions:

  • 5 + 8758661 = 8758666
  • 29 + 8758637 = 8758666
  • 83 + 8758583 = 8758666
  • 89 + 8758577 = 8758666
  • 167 + 8758499 = 8758666
  • 233 + 8758433 = 8758666
  • 239 + 8758427 = 8758666
  • 353 + 8758313 = 8758666

Showing the first eight; more decompositions exist.
