Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147397600, here are decompositions:

  • 11 + 2147397589 = 2147397600
  • 13 + 2147397587 = 2147397600
  • 31 + 2147397569 = 2147397600
  • 37 + 2147397563 = 2147397600
  • 43 + 2147397557 = 2147397600
  • 59 + 2147397541 = 2147397600
  • 137 + 2147397463 = 2147397600
  • 157 + 2147397443 = 2147397600

Showing the first eight; more decompositions exist.
