Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617784, here are decompositions:

  • 31 + 8617753 = 8617784
  • 103 + 8617681 = 8617784
  • 157 + 8617627 = 8617784
  • 223 + 8617561 = 8617784
  • 271 + 8617513 = 8617784
  • 337 + 8617447 = 8617784
  • 367 + 8617417 = 8617784
  • 457 + 8617327 = 8617784

Showing the first eight; more decompositions exist.
