Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492976, here are decompositions:

17 + 2147492959 = 2147492976
37 + 2147492939 = 2147492976
47 + 2147492929 = 2147492976
53 + 2147492923 = 2147492976
337 + 2147492639 = 2147492976
367 + 2147492609 = 2147492976
379 + 2147492597 = 2147492976
443 + 2147492533 = 2147492976

Showing the first eight; more decompositions exist.
