Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147375256, here are decompositions:

  • 7 + 2147375249 = 2147375256
  • 83 + 2147375173 = 2147375256
  • 107 + 2147375149 = 2147375256
  • 137 + 2147375119 = 2147375256
  • 157 + 2147375099 = 2147375256
  • 167 + 2147375089 = 2147375256
  • 263 + 2147374993 = 2147375256
  • 269 + 2147374987 = 2147375256

Showing the first eight; more decompositions exist.
