Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467858, here are decompositions:

  • 89 + 2147467769 = 2147467858
  • 191 + 2147467667 = 2147467858
  • 227 + 2147467631 = 2147467858
  • 479 + 2147467379 = 2147467858
  • 491 + 2147467367 = 2147467858
  • 647 + 2147467211 = 2147467858
  • 911 + 2147466947 = 2147467858
  • 1217 + 2147466641 = 2147467858

Showing the first eight; more decompositions exist.
