Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469468, here are decompositions:

  • 5 + 2147469463 = 2147469468
  • 19 + 2147469449 = 2147469468
  • 47 + 2147469421 = 2147469468
  • 139 + 2147469329 = 2147469468
  • 197 + 2147469271 = 2147469468
  • 229 + 2147469239 = 2147469468
  • 239 + 2147469229 = 2147469468
  • 281 + 2147469187 = 2147469468

Showing the first eight; more decompositions exist.
