Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294993278, here are decompositions:

11 + 4294993267 = 4294993278
137 + 4294993141 = 4294993278
151 + 4294993127 = 4294993278
157 + 4294993121 = 4294993278
179 + 4294993099 = 4294993278
307 + 4294992971 = 4294993278
337 + 4294992941 = 4294993278
379 + 4294992899 = 4294993278

Showing the first eight; more decompositions exist.
