Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497530, here are decompositions:

7 + 2147497523 = 2147497530
23 + 2147497507 = 2147497530
37 + 2147497493 = 2147497530
41 + 2147497489 = 2147497530
71 + 2147497459 = 2147497530
83 + 2147497447 = 2147497530
127 + 2147497403 = 2147497530
137 + 2147497393 = 2147497530

Showing the first eight; more decompositions exist.
