Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469918, here are decompositions:

  • 37 + 2147469881 = 2147469918
  • 89 + 2147469829 = 2147469918
  • 101 + 2147469817 = 2147469918
  • 137 + 2147469781 = 2147469918
  • 239 + 2147469679 = 2147469918
  • 281 + 2147469637 = 2147469918
  • 397 + 2147469521 = 2147469918
  • 499 + 2147469419 = 2147469918

Showing the first eight; more decompositions exist.
