Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469782, here are decompositions:

  • 79 + 2147469703 = 2147469782
  • 103 + 2147469679 = 2147469782
  • 163 + 2147469619 = 2147469782
  • 229 + 2147469553 = 2147469782
  • 499 + 2147469283 = 2147469782
  • 709 + 2147469073 = 2147469782
  • 811 + 2147468971 = 2147469782
  • 859 + 2147468923 = 2147469782

Showing the first eight; more decompositions exist.
