Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638294, here are decompositions:

  • 3 + 8638291 = 8638294
  • 11 + 8638283 = 8638294
  • 17 + 8638277 = 8638294
  • 47 + 8638247 = 8638294
  • 53 + 8638241 = 8638294
  • 107 + 8638187 = 8638294
  • 173 + 8638121 = 8638294
  • 227 + 8638067 = 8638294

Showing the first eight; more decompositions exist.
