Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489516, here are decompositions:

13 + 2147489503 = 2147489516
43 + 2147489473 = 2147489516
79 + 2147489437 = 2147489516
313 + 2147489203 = 2147489516
373 + 2147489143 = 2147489516
433 + 2147489083 = 2147489516
439 + 2147489077 = 2147489516
457 + 2147489059 = 2147489516

Showing the first eight; more decompositions exist.
