Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294993940, here are decompositions:

103 + 4294993837 = 4294993940
163 + 4294993777 = 4294993940
199 + 4294993741 = 4294993940
283 + 4294993657 = 4294993940
439 + 4294993501 = 4294993940
541 + 4294993399 = 4294993940
607 + 4294993333 = 4294993940
613 + 4294993327 = 4294993940

Showing the first eight; more decompositions exist.
