Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469556, here are decompositions:

  • 3 + 2147469553 = 2147469556
  • 107 + 2147469449 = 2147469556
  • 137 + 2147469419 = 2147469556
  • 227 + 2147469329 = 2147469556
  • 293 + 2147469263 = 2147469556
  • 317 + 2147469239 = 2147469556
  • 383 + 2147469173 = 2147469556
  • 443 + 2147469113 = 2147469556

Showing the first eight; more decompositions exist.
