Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467642, here are decompositions:

  • 3 + 2147467639 = 2147467642
  • 11 + 2147467631 = 2147467642
  • 59 + 2147467583 = 2147467642
  • 83 + 2147467559 = 2147467642
  • 149 + 2147467493 = 2147467642
  • 179 + 2147467463 = 2147467642
  • 239 + 2147467403 = 2147467642
  • 263 + 2147467379 = 2147467642

Showing the first eight; more decompositions exist.
