Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469222, here are decompositions:

  • 43 + 2147469179 = 2147469222
  • 89 + 2147469133 = 2147469222
  • 109 + 2147469113 = 2147469222
  • 149 + 2147469073 = 2147469222
  • 181 + 2147469041 = 2147469222
  • 229 + 2147468993 = 2147469222
  • 251 + 2147468971 = 2147469222
  • 313 + 2147468909 = 2147469222

Showing the first eight; more decompositions exist.
