Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499966, here are decompositions:

  • 5 + 2147499961 = 2147499966
  • 13 + 2147499953 = 2147499966
  • 43 + 2147499923 = 2147499966
  • 83 + 2147499883 = 2147499966
  • 103 + 2147499863 = 2147499966
  • 137 + 2147499829 = 2147499966
  • 239 + 2147499727 = 2147499966
  • 263 + 2147499703 = 2147499966

Showing the first eight; more decompositions exist.
