Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8676920, here are decompositions:

  • 37 + 8676883 = 8676920
  • 73 + 8676847 = 8676920
  • 139 + 8676781 = 8676920
  • 151 + 8676769 = 8676920
  • 163 + 8676757 = 8676920
  • 199 + 8676721 = 8676920
  • 229 + 8676691 = 8676920
  • 277 + 8676643 = 8676920

Showing the first eight; more decompositions exist.
