Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489966, here are decompositions:

19 + 2147489947 = 2147489966
67 + 2147489899 = 2147489966
313 + 2147489653 = 2147489966
379 + 2147489587 = 2147489966
463 + 2147489503 = 2147489966
619 + 2147489347 = 2147489966
823 + 2147489143 = 2147489966
877 + 2147489089 = 2147489966

Showing the first eight; more decompositions exist.
