Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501208, here are decompositions:

  • 31 + 2147501177 = 2147501208
  • 79 + 2147501129 = 2147501208
  • 107 + 2147501101 = 2147501208
  • 131 + 2147501077 = 2147501208
  • 199 + 2147501009 = 2147501208
  • 227 + 2147500981 = 2147501208
  • 271 + 2147500937 = 2147501208
  • 277 + 2147500931 = 2147501208

Showing the first eight; more decompositions exist.
