Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485174, here are decompositions:

41 + 2147485133 = 2147485174
53 + 2147485121 = 2147485174
101 + 2147485073 = 2147485174
353 + 2147484821 = 2147485174
383 + 2147484791 = 2147485174
557 + 2147484617 = 2147485174
563 + 2147484611 = 2147485174
647 + 2147484527 = 2147485174

Showing the first eight; more decompositions exist.
