Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469916, here are decompositions:

  • 257 + 2147469659 = 2147469916
  • 467 + 2147469449 = 2147469916
  • 569 + 2147469347 = 2147469916
  • 587 + 2147469329 = 2147469916
  • 653 + 2147469263 = 2147469916
  • 677 + 2147469239 = 2147469916
  • 743 + 2147469173 = 2147469916
  • 827 + 2147469089 = 2147469916

Showing the first eight; more decompositions exist.
