Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666520, here are decompositions:

  • 7 + 8666513 = 8666520
  • 19 + 8666501 = 8666520
  • 29 + 8666491 = 8666520
  • 41 + 8666479 = 8666520
  • 43 + 8666477 = 8666520
  • 61 + 8666459 = 8666520
  • 89 + 8666431 = 8666520
  • 101 + 8666419 = 8666520

Showing the first eight; more decompositions exist.
