Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638792, here are decompositions:

  • 59 + 8638733 = 8638792
  • 101 + 8638691 = 8638792
  • 131 + 8638661 = 8638792
  • 311 + 8638481 = 8638792
  • 389 + 8638403 = 8638792
  • 419 + 8638373 = 8638792
  • 443 + 8638349 = 8638792
  • 509 + 8638283 = 8638792

Showing the first eight; more decompositions exist.
