Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469908, here are decompositions:

  • 79 + 2147469829 = 2147469908
  • 127 + 2147469781 = 2147469908
  • 229 + 2147469679 = 2147469908
  • 271 + 2147469637 = 2147469908
  • 487 + 2147469421 = 2147469908
  • 751 + 2147469157 = 2147469908
  • 907 + 2147469001 = 2147469908
  • 937 + 2147468971 = 2147469908

Showing the first eight; more decompositions exist.
