Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486178, here are decompositions:

  • 31 + 2147486147 = 2147486178
  • 67 + 2147486111 = 2147486178
  • 157 + 2147486021 = 2147486178
  • 179 + 2147485999 = 2147486178
  • 239 + 2147485939 = 2147486178
  • 251 + 2147485927 = 2147486178
  • 281 + 2147485897 = 2147486178
  • 307 + 2147485871 = 2147486178

Showing the first eight; more decompositions exist.
