Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469272, here are decompositions:

  • 43 + 2147469229 = 2147469272
  • 139 + 2147469133 = 2147469272
  • 199 + 2147469073 = 2147469272
  • 271 + 2147469001 = 2147469272
  • 349 + 2147468923 = 2147469272
  • 439 + 2147468833 = 2147469272
  • 463 + 2147468809 = 2147469272
  • 499 + 2147468773 = 2147469272

Showing the first eight; more decompositions exist.
