Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497956, here are decompositions:

  • 7 + 2147497949 = 2147497956
  • 13 + 2147497943 = 2147497956
  • 17 + 2147497939 = 2147497956
  • 67 + 2147497889 = 2147497956
  • 199 + 2147497757 = 2147497956
  • 223 + 2147497733 = 2147497956
  • 239 + 2147497717 = 2147497956
  • 257 + 2147497699 = 2147497956

Showing the first eight; more decompositions exist.
