Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485516, here are decompositions:

  • 17 + 2147485499 = 2147485516
  • 83 + 2147485433 = 2147485516
  • 173 + 2147485343 = 2147485516
  • 179 + 2147485337 = 2147485516
  • 257 + 2147485259 = 2147485516
  • 263 + 2147485253 = 2147485516
  • 269 + 2147485247 = 2147485516
  • 383 + 2147485133 = 2147485516

Showing the first eight; more decompositions exist.
