Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501172, here are decompositions:

  • 29 + 2147501143 = 2147501172
  • 41 + 2147501131 = 2147501172
  • 43 + 2147501129 = 2147501172
  • 71 + 2147501101 = 2147501172
  • 83 + 2147501089 = 2147501172
  • 163 + 2147501009 = 2147501172
  • 191 + 2147500981 = 2147501172
  • 241 + 2147500931 = 2147501172

Showing the first eight; more decompositions exist.
