Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469956, here are decompositions:

  • 7 + 2147469949 = 2147469956
  • 13 + 2147469943 = 2147469956
  • 127 + 2147469829 = 2147469956
  • 139 + 2147469817 = 2147469956
  • 277 + 2147469679 = 2147469956
  • 337 + 2147469619 = 2147469956
  • 673 + 2147469283 = 2147469956
  • 727 + 2147469229 = 2147469956

Showing the first eight; more decompositions exist.
