Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469284, here are decompositions:

  • 13 + 2147469271 = 2147469284
  • 97 + 2147469187 = 2147469284
  • 127 + 2147469157 = 2147469284
  • 151 + 2147469133 = 2147469284
  • 211 + 2147469073 = 2147469284
  • 277 + 2147469007 = 2147469284
  • 283 + 2147469001 = 2147469284
  • 313 + 2147468971 = 2147469284

Showing the first eight; more decompositions exist.
