Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489522, here are decompositions:

19 + 2147489503 = 2147489522
223 + 2147489299 = 2147489522
379 + 2147489143 = 2147489522
433 + 2147489089 = 2147489522
439 + 2147489083 = 2147489522
463 + 2147489059 = 2147489522
499 + 2147489023 = 2147489522
1093 + 2147488429 = 2147489522

Showing the first eight; more decompositions exist.
