Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294993668, here are decompositions:

11 + 4294993657 = 4294993668
19 + 4294993649 = 4294993668
61 + 4294993607 = 4294993668
131 + 4294993537 = 4294993668
151 + 4294993517 = 4294993668
167 + 4294993501 = 4294993668
269 + 4294993399 = 4294993668
271 + 4294993397 = 4294993668

Showing the first eight; more decompositions exist.
