Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294956928, here are decompositions:

5 + 4294956923 = 4294956928
47 + 4294956881 = 4294956928
89 + 4294956839 = 4294956928
239 + 4294956689 = 4294956928
257 + 4294956671 = 4294956928
359 + 4294956569 = 4294956928
419 + 4294956509 = 4294956928
461 + 4294956467 = 4294956928

Showing the first eight; more decompositions exist.
