Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497544, here are decompositions:

37 + 2147497507 = 2147497544
97 + 2147497447 = 2147497544
151 + 2147497393 = 2147497544
223 + 2147497321 = 2147497544
307 + 2147497237 = 2147497544
463 + 2147497081 = 2147497544
547 + 2147496997 = 2147497544
607 + 2147496937 = 2147497544

Showing the first eight; more decompositions exist.
