Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469378, here are decompositions:

  • 31 + 2147469347 = 2147469378
  • 107 + 2147469271 = 2147469378
  • 139 + 2147469239 = 2147469378
  • 149 + 2147469229 = 2147469378
  • 191 + 2147469187 = 2147469378
  • 199 + 2147469179 = 2147469378
  • 277 + 2147469101 = 2147469378
  • 311 + 2147469067 = 2147469378

Showing the first eight; more decompositions exist.
