Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147475168, here are decompositions:

  • 19 + 2147475149 = 2147475168
  • 61 + 2147475107 = 2147475168
  • 107 + 2147475061 = 2147475168
  • 239 + 2147474929 = 2147475168
  • 277 + 2147474891 = 2147475168
  • 281 + 2147474887 = 2147475168
  • 317 + 2147474851 = 2147475168
  • 331 + 2147474837 = 2147475168

Showing the first eight; more decompositions exist.
