Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467768, here are decompositions:

  • 71 + 2147467697 = 2147467768
  • 101 + 2147467667 = 2147467768
  • 137 + 2147467631 = 2147467768
  • 389 + 2147467379 = 2147467768
  • 401 + 2147467367 = 2147467768
  • 557 + 2147467211 = 2147467768
  • 599 + 2147467169 = 2147467768
  • 647 + 2147467121 = 2147467768

Showing the first eight; more decompositions exist.
