Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469988, here are decompositions:

  • 5 + 2147469983 = 2147469988
  • 71 + 2147469917 = 2147469988
  • 107 + 2147469881 = 2147469988
  • 359 + 2147469629 = 2147469988
  • 467 + 2147469521 = 2147469988
  • 569 + 2147469419 = 2147469988
  • 641 + 2147469347 = 2147469988
  • 659 + 2147469329 = 2147469988

Showing the first eight; more decompositions exist.
