Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473964, here are decompositions:

  • 43 + 2147473921 = 2147473964
  • 67 + 2147473897 = 2147473964
  • 73 + 2147473891 = 2147473964
  • 127 + 2147473837 = 2147473964
  • 397 + 2147473567 = 2147473964
  • 487 + 2147473477 = 2147473964
  • 613 + 2147473351 = 2147473964
  • 673 + 2147473291 = 2147473964

Showing the first eight; more decompositions exist.
