Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294993820, here are decompositions:

43 + 4294993777 = 4294993820
79 + 4294993741 = 4294993820
97 + 4294993723 = 4294993820
127 + 4294993693 = 4294993820
163 + 4294993657 = 4294993820
283 + 4294993537 = 4294993820
307 + 4294993513 = 4294993820
421 + 4294993399 = 4294993820

Showing the first eight; more decompositions exist.
