Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485628, here are decompositions:

37 + 2147485591 = 2147485628
61 + 2147485567 = 2147485628
181 + 2147485447 = 2147485628
271 + 2147485357 = 2147485628
367 + 2147485261 = 2147485628
439 + 2147485189 = 2147485628
487 + 2147485141 = 2147485628
571 + 2147485057 = 2147485628

Showing the first eight; more decompositions exist.
