Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469402, here are decompositions:

  • 73 + 2147469329 = 2147469402
  • 131 + 2147469271 = 2147469402
  • 139 + 2147469263 = 2147469402
  • 163 + 2147469239 = 2147469402
  • 173 + 2147469229 = 2147469402
  • 223 + 2147469179 = 2147469402
  • 229 + 2147469173 = 2147469402
  • 269 + 2147469133 = 2147469402

Showing the first eight; more decompositions exist.
