Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469178, here are decompositions:

  • 5 + 2147469173 = 2147469178
  • 47 + 2147469131 = 2147469178
  • 89 + 2147469089 = 2147469178
  • 131 + 2147469047 = 2147469178
  • 137 + 2147469041 = 2147469178
  • 191 + 2147468987 = 2147469178
  • 269 + 2147468909 = 2147469178
  • 317 + 2147468861 = 2147469178

Showing the first eight; more decompositions exist.
