Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294991568, here are decompositions:

11 + 4294991557 = 4294991568
17 + 4294991551 = 4294991568
29 + 4294991539 = 4294991568
47 + 4294991521 = 4294991568
59 + 4294991509 = 4294991568
61 + 4294991507 = 4294991568
71 + 4294991497 = 4294991568
97 + 4294991471 = 4294991568

Showing the first eight; more decompositions exist.
