Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484928, here are decompositions:

59 + 2147484869 = 2147484928
107 + 2147484821 = 2147484928
137 + 2147484791 = 2147484928
311 + 2147484617 = 2147484928
317 + 2147484611 = 2147484928
359 + 2147484569 = 2147484928
401 + 2147484527 = 2147484928
467 + 2147484461 = 2147484928

Showing the first eight; more decompositions exist.
