Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147494678, here are decompositions:

  • 5 + 2147494673 = 2147494678
  • 107 + 2147494571 = 2147494678
  • 149 + 2147494529 = 2147494678
  • 167 + 2147494511 = 2147494678
  • 191 + 2147494487 = 2147494678
  • 269 + 2147494409 = 2147494678
  • 419 + 2147494259 = 2147494678
  • 467 + 2147494211 = 2147494678

Showing the first eight; more decompositions exist.
