Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484856, here are decompositions:

5 + 2147484851 = 2147484856
239 + 2147484617 = 2147484856
479 + 2147484377 = 2147484856
617 + 2147484239 = 2147484856
653 + 2147484203 = 2147484856
659 + 2147484197 = 2147484856
773 + 2147484083 = 2147484856
857 + 2147483999 = 2147484856

Showing the first eight; more decompositions exist.
