Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469392, here are decompositions:

  • 109 + 2147469283 = 2147469392
  • 163 + 2147469229 = 2147469392
  • 421 + 2147468971 = 2147469392
  • 613 + 2147468779 = 2147469392
  • 619 + 2147468773 = 2147469392
  • 829 + 2147468563 = 2147469392
  • 1051 + 2147468341 = 2147469392
  • 1123 + 2147468269 = 2147469392

Showing the first eight; more decompositions exist.
