Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473072, here are decompositions:

  • 11 + 2147473061 = 2147473072
  • 23 + 2147473049 = 2147473072
  • 113 + 2147472959 = 2147473072
  • 149 + 2147472923 = 2147473072
  • 179 + 2147472893 = 2147473072
  • 359 + 2147472713 = 2147473072
  • 383 + 2147472689 = 2147473072
  • 389 + 2147472683 = 2147473072

Showing the first eight; more decompositions exist.
