Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469686, here are decompositions:

  • 7 + 2147469679 = 2147469686
  • 67 + 2147469619 = 2147469686
  • 223 + 2147469463 = 2147469686
  • 457 + 2147469229 = 2147469686
  • 499 + 2147469187 = 2147469686
  • 613 + 2147469073 = 2147469686
  • 619 + 2147469067 = 2147469686
  • 853 + 2147468833 = 2147469686

Showing the first eight; more decompositions exist.
