Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294979388, here are decompositions:

5 + 4294979383 = 4294979388
59 + 4294979329 = 4294979388
67 + 4294979321 = 4294979388
101 + 4294979287 = 4294979388
151 + 4294979237 = 4294979388
181 + 4294979207 = 4294979388
229 + 4294979159 = 4294979388
277 + 4294979111 = 4294979388

Showing the first eight; more decompositions exist.
