Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484778, here are decompositions:

137 + 2147484641 = 2147484778
167 + 2147484611 = 2147484778
251 + 2147484527 = 2147484778
317 + 2147484461 = 2147484778
401 + 2147484377 = 2147484778
557 + 2147484221 = 2147484778
617 + 2147484161 = 2147484778
827 + 2147483951 = 2147484778

Showing the first eight; more decompositions exist.
