Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469834, here are decompositions:

  • 5 + 2147469829 = 2147469834
  • 11 + 2147469823 = 2147469834
  • 17 + 2147469817 = 2147469834
  • 53 + 2147469781 = 2147469834
  • 131 + 2147469703 = 2147469834
  • 197 + 2147469637 = 2147469834
  • 241 + 2147469593 = 2147469834
  • 281 + 2147469553 = 2147469834

Showing the first eight; more decompositions exist.
