Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489666, here are decompositions:

13 + 2147489653 = 2147489666
79 + 2147489587 = 2147489666
163 + 2147489503 = 2147489666
193 + 2147489473 = 2147489666
229 + 2147489437 = 2147489666
367 + 2147489299 = 2147489666
463 + 2147489203 = 2147489666
523 + 2147489143 = 2147489666

Showing the first eight; more decompositions exist.
