Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497726, here are decompositions:

  • 29 + 2147497697 = 2147497726
  • 167 + 2147497559 = 2147497726
  • 233 + 2147497493 = 2147497726
  • 593 + 2147497133 = 2147497726
  • 683 + 2147497043 = 2147497726
  • 809 + 2147496917 = 2147497726
  • 863 + 2147496863 = 2147497726
  • 887 + 2147496839 = 2147497726

Showing the first eight; more decompositions exist.
