Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469646, here are decompositions:

  • 17 + 2147469629 = 2147469646
  • 53 + 2147469593 = 2147469646
  • 197 + 2147469449 = 2147469646
  • 227 + 2147469419 = 2147469646
  • 317 + 2147469329 = 2147469646
  • 383 + 2147469263 = 2147469646
  • 467 + 2147469179 = 2147469646
  • 557 + 2147469089 = 2147469646

Showing the first eight; more decompositions exist.
