Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147466566, here are decompositions:

  • 19 + 2147466547 = 2147466566
  • 79 + 2147466487 = 2147466566
  • 103 + 2147466463 = 2147466566
  • 109 + 2147466457 = 2147466566
  • 127 + 2147466439 = 2147466566
  • 139 + 2147466427 = 2147466566
  • 229 + 2147466337 = 2147466566
  • 283 + 2147466283 = 2147466566

Showing the first eight; more decompositions exist.
