Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497730, here are decompositions:

13 + 2147497717 = 2147497730
31 + 2147497699 = 2147497730
67 + 2147497663 = 2147497730
223 + 2147497507 = 2147497730
241 + 2147497489 = 2147497730
271 + 2147497459 = 2147497730
283 + 2147497447 = 2147497730
337 + 2147497393 = 2147497730

Showing the first eight; more decompositions exist.
