Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469810, here are decompositions:

  • 29 + 2147469781 = 2147469810
  • 107 + 2147469703 = 2147469810
  • 131 + 2147469679 = 2147469810
  • 151 + 2147469659 = 2147469810
  • 173 + 2147469637 = 2147469810
  • 181 + 2147469629 = 2147469810
  • 191 + 2147469619 = 2147469810
  • 257 + 2147469553 = 2147469810

Showing the first eight; more decompositions exist.
