Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469342, here are decompositions:

  • 13 + 2147469329 = 2147469342
  • 59 + 2147469283 = 2147469342
  • 71 + 2147469271 = 2147469342
  • 79 + 2147469263 = 2147469342
  • 103 + 2147469239 = 2147469342
  • 113 + 2147469229 = 2147469342
  • 163 + 2147469179 = 2147469342
  • 211 + 2147469131 = 2147469342

Showing the first eight; more decompositions exist.
