Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469798, here are decompositions:

  • 17 + 2147469781 = 2147469798
  • 139 + 2147469659 = 2147469798
  • 179 + 2147469619 = 2147469798
  • 277 + 2147469521 = 2147469798
  • 307 + 2147469491 = 2147469798
  • 349 + 2147469449 = 2147469798
  • 379 + 2147469419 = 2147469798
  • 569 + 2147469229 = 2147469798

Showing the first eight; more decompositions exist.
