Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294993788, here are decompositions:

11 + 4294993777 = 4294993788
17 + 4294993771 = 4294993788
47 + 4294993741 = 4294993788
61 + 4294993727 = 4294993788
67 + 4294993721 = 4294993788
97 + 4294993691 = 4294993788
131 + 4294993657 = 4294993788
139 + 4294993649 = 4294993788

Showing the first eight; more decompositions exist.
