Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473520, here are decompositions:

  • 37 + 2147473483 = 2147473520
  • 43 + 2147473477 = 2147473520
  • 151 + 2147473369 = 2147473520
  • 223 + 2147473297 = 2147473520
  • 229 + 2147473291 = 2147473520
  • 733 + 2147472787 = 2147473520
  • 769 + 2147472751 = 2147473520
  • 823 + 2147472697 = 2147473520

Showing the first eight; more decompositions exist.
