Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294993218, here are decompositions:

17 + 4294993201 = 4294993218
97 + 4294993121 = 4294993218
199 + 4294993019 = 4294993218
239 + 4294992979 = 4294993218
277 + 4294992941 = 4294993218
421 + 4294992797 = 4294993218
541 + 4294992677 = 4294993218
557 + 4294992661 = 4294993218

Showing the first eight; more decompositions exist.
