Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147374646, here are decompositions:

  • 7 + 2147374639 = 2147374646
  • 13 + 2147374633 = 2147374646
  • 127 + 2147374519 = 2147374646
  • 349 + 2147374297 = 2147374646
  • 367 + 2147374279 = 2147374646
  • 463 + 2147374183 = 2147374646
  • 1039 + 2147373607 = 2147374646
  • 1063 + 2147373583 = 2147374646

Showing the first eight; more decompositions exist.
