Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147377968, here are decompositions:

  • 7 + 2147377961 = 2147377968
  • 17 + 2147377951 = 2147377968
  • 41 + 2147377927 = 2147377968
  • 89 + 2147377879 = 2147377968
  • 97 + 2147377871 = 2147377968
  • 179 + 2147377789 = 2147377968
  • 181 + 2147377787 = 2147377968
  • 227 + 2147377741 = 2147377968

Showing the first eight; more decompositions exist.
