Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294993808, here are decompositions:

31 + 4294993777 = 4294993808
37 + 4294993771 = 4294993808
67 + 4294993741 = 4294993808
151 + 4294993657 = 4294993808
271 + 4294993537 = 4294993808
307 + 4294993501 = 4294993808
409 + 4294993399 = 4294993808
541 + 4294993267 = 4294993808

Showing the first eight; more decompositions exist.
