Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485408, here are decompositions:

71 + 2147485337 = 2147485408
149 + 2147485259 = 2147485408
227 + 2147485181 = 2147485408
311 + 2147485097 = 2147485408
479 + 2147484929 = 2147485408
557 + 2147484851 = 2147485408
587 + 2147484821 = 2147485408
617 + 2147484791 = 2147485408

Showing the first eight; more decompositions exist.
