Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497218, here are decompositions:

  • 17 + 2147497201 = 2147497218
  • 137 + 2147497081 = 2147497218
  • 179 + 2147497039 = 2147497218
  • 199 + 2147497019 = 2147497218
  • 239 + 2147496979 = 2147497218
  • 257 + 2147496961 = 2147497218
  • 277 + 2147496941 = 2147497218
  • 281 + 2147496937 = 2147497218

Showing the first eight; more decompositions exist.
