Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483870, here are decompositions:

  • 3 + 2147483867 = 2147483870
  • 13 + 2147483857 = 2147483870
  • 127 + 2147483743 = 2147483870
  • 157 + 2147483713 = 2147483870
  • 211 + 2147483659 = 2147483870
  • 223 + 2147483647 = 2147483870
  • 241 + 2147483629 = 2147483870
  • 283 + 2147483587 = 2147483870

Showing the first eight; more decompositions exist.
