Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467656, here are decompositions:

  • 17 + 2147467639 = 2147467656
  • 29 + 2147467627 = 2147467656
  • 73 + 2147467583 = 2147467656
  • 97 + 2147467559 = 2147467656
  • 163 + 2147467493 = 2147467656
  • 193 + 2147467463 = 2147467656
  • 263 + 2147467393 = 2147467656
  • 277 + 2147467379 = 2147467656

Showing the first eight; more decompositions exist.
