Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638762, here are decompositions:

  • 29 + 8638733 = 8638762
  • 71 + 8638691 = 8638762
  • 101 + 8638661 = 8638762
  • 179 + 8638583 = 8638762
  • 281 + 8638481 = 8638762
  • 311 + 8638451 = 8638762
  • 359 + 8638403 = 8638762
  • 383 + 8638379 = 8638762

Showing the first eight; more decompositions exist.
