Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484892, here are decompositions:

23 + 2147484869 = 2147484892
41 + 2147484851 = 2147484892
71 + 2147484821 = 2147484892
101 + 2147484791 = 2147484892
251 + 2147484641 = 2147484892
281 + 2147484611 = 2147484892
401 + 2147484491 = 2147484892
431 + 2147484461 = 2147484892

Showing the first eight; more decompositions exist.
