Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468946, here are decompositions:

  • 13 + 2147468933 = 2147468946
  • 23 + 2147468923 = 2147468946
  • 37 + 2147468909 = 2147468946
  • 59 + 2147468887 = 2147468946
  • 113 + 2147468833 = 2147468946
  • 137 + 2147468809 = 2147468946
  • 163 + 2147468783 = 2147468946
  • 167 + 2147468779 = 2147468946

Showing the first eight; more decompositions exist.
