Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469880, here are decompositions:

  • 251 + 2147469629 = 2147469880
  • 359 + 2147469521 = 2147469880
  • 389 + 2147469491 = 2147469880
  • 431 + 2147469449 = 2147469880
  • 461 + 2147469419 = 2147469880
  • 617 + 2147469263 = 2147469880
  • 641 + 2147469239 = 2147469880
  • 701 + 2147469179 = 2147469880

Showing the first eight; more decompositions exist.
