Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638462, here are decompositions:

  • 5 + 8638457 = 8638462
  • 11 + 8638451 = 8638462
  • 59 + 8638403 = 8638462
  • 83 + 8638379 = 8638462
  • 89 + 8638373 = 8638462
  • 113 + 8638349 = 8638462
  • 179 + 8638283 = 8638462
  • 233 + 8638229 = 8638462

Showing the first eight; more decompositions exist.
