Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469938, here are decompositions:

  • 109 + 2147469829 = 2147469938
  • 157 + 2147469781 = 2147469938
  • 709 + 2147469229 = 2147469938
  • 751 + 2147469187 = 2147469938
  • 937 + 2147469001 = 2147469938
  • 967 + 2147468971 = 2147469938
  • 1051 + 2147468887 = 2147469938
  • 1129 + 2147468809 = 2147469938

Showing the first eight; more decompositions exist.
