Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147377950, here are decompositions:

  • 7 + 2147377943 = 2147377950
  • 23 + 2147377927 = 2147377950
  • 71 + 2147377879 = 2147377950
  • 79 + 2147377871 = 2147377950
  • 163 + 2147377787 = 2147377950
  • 197 + 2147377753 = 2147377950
  • 251 + 2147377699 = 2147377950
  • 271 + 2147377679 = 2147377950

Showing the first eight; more decompositions exist.
