Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147480970, here are decompositions:

  • 13 + 2147480957 = 2147480970
  • 29 + 2147480941 = 2147480970
  • 43 + 2147480927 = 2147480970
  • 71 + 2147480899 = 2147480970
  • 73 + 2147480897 = 2147480970
  • 127 + 2147480843 = 2147480970
  • 179 + 2147480791 = 2147480970
  • 223 + 2147480747 = 2147480970

Showing the first eight; more decompositions exist.
