Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294993478, here are decompositions:

79 + 4294993399 = 4294993478
151 + 4294993327 = 4294993478
211 + 4294993267 = 4294993478
277 + 4294993201 = 4294993478
337 + 4294993141 = 4294993478
379 + 4294993099 = 4294993478
499 + 4294992979 = 4294993478
1039 + 4294992439 = 4294993478

Showing the first eight; more decompositions exist.
