Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294993778, here are decompositions:

7 + 4294993771 = 4294993778
37 + 4294993741 = 4294993778
241 + 4294993537 = 4294993778
277 + 4294993501 = 4294993778
379 + 4294993399 = 4294993778
487 + 4294993291 = 4294993778
577 + 4294993201 = 4294993778
937 + 4294992841 = 4294993778

Showing the first eight; more decompositions exist.
