Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485670, here are decompositions:

79 + 2147485591 = 2147485670
97 + 2147485573 = 2147485670
103 + 2147485567 = 2147485670
223 + 2147485447 = 2147485670
313 + 2147485357 = 2147485670
409 + 2147485261 = 2147485670
613 + 2147485057 = 2147485670
709 + 2147484961 = 2147485670

Showing the first eight; more decompositions exist.
