Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294993990, here are decompositions:

11 + 4294993979 = 4294993990
29 + 4294993961 = 4294993990
137 + 4294993853 = 4294993990
197 + 4294993793 = 4294993990
251 + 4294993739 = 4294993990
263 + 4294993727 = 4294993990
269 + 4294993721 = 4294993990
383 + 4294993607 = 4294993990

Showing the first eight; more decompositions exist.
