Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469826, here are decompositions:

  • 3 + 2147469823 = 2147469826
  • 167 + 2147469659 = 2147469826
  • 197 + 2147469629 = 2147469826
  • 233 + 2147469593 = 2147469826
  • 479 + 2147469347 = 2147469826
  • 563 + 2147469263 = 2147469826
  • 587 + 2147469239 = 2147469826
  • 647 + 2147469179 = 2147469826

Showing the first eight; more decompositions exist.
