Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668394, here are decompositions:

  • 13 + 8668381 = 8668394
  • 37 + 8668357 = 8668394
  • 127 + 8668267 = 8668394
  • 193 + 8668201 = 8668394
  • 283 + 8668111 = 8668394
  • 313 + 8668081 = 8668394
  • 331 + 8668063 = 8668394
  • 337 + 8668057 = 8668394

Showing the first eight; more decompositions exist.
