Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501166, here are decompositions:

  • 23 + 2147501143 = 2147501166
  • 37 + 2147501129 = 2147501166
  • 89 + 2147501077 = 2147501166
  • 157 + 2147501009 = 2147501166
  • 179 + 2147500987 = 2147501166
  • 229 + 2147500937 = 2147501166
  • 257 + 2147500909 = 2147501166
  • 277 + 2147500889 = 2147501166

Showing the first eight; more decompositions exist.
