Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147474970, here are decompositions:

  • 7 + 2147474963 = 2147474970
  • 19 + 2147474951 = 2147474970
  • 23 + 2147474947 = 2147474970
  • 41 + 2147474929 = 2147474970
  • 79 + 2147474891 = 2147474970
  • 83 + 2147474887 = 2147474970
  • 89 + 2147474881 = 2147474970
  • 127 + 2147474843 = 2147474970

Showing the first eight; more decompositions exist.
