Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467666, here are decompositions:

  • 83 + 2147467583 = 2147467666
  • 107 + 2147467559 = 2147467666
  • 173 + 2147467493 = 2147467666
  • 263 + 2147467403 = 2147467666
  • 503 + 2147467163 = 2147467666
  • 599 + 2147467067 = 2147467666
  • 719 + 2147466947 = 2147467666
  • 797 + 2147466869 = 2147467666

Showing the first eight; more decompositions exist.
