Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501142, here are decompositions:

  • 11 + 2147501131 = 2147501142
  • 13 + 2147501129 = 2147501142
  • 41 + 2147501101 = 2147501142
  • 53 + 2147501089 = 2147501142
  • 211 + 2147500931 = 2147501142
  • 233 + 2147500909 = 2147501142
  • 263 + 2147500879 = 2147501142
  • 271 + 2147500871 = 2147501142

Showing the first eight; more decompositions exist.
