Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498664, here are decompositions:

  • 5 + 2147498659 = 2147498664
  • 7 + 2147498657 = 2147498664
  • 11 + 2147498653 = 2147498664
  • 37 + 2147498627 = 2147498664
  • 71 + 2147498593 = 2147498664
  • 83 + 2147498581 = 2147498664
  • 163 + 2147498501 = 2147498664
  • 193 + 2147498471 = 2147498664

Showing the first eight; more decompositions exist.
