Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485814, here are decompositions:

7 + 2147485807 = 2147485814
127 + 2147485687 = 2147485814
223 + 2147485591 = 2147485814
241 + 2147485573 = 2147485814
367 + 2147485447 = 2147485814
433 + 2147485381 = 2147485814
457 + 2147485357 = 2147485814
547 + 2147485267 = 2147485814

Showing the first eight; more decompositions exist.
