Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294993638, here are decompositions:

31 + 4294993607 = 4294993638
101 + 4294993537 = 4294993638
137 + 4294993501 = 4294993638
239 + 4294993399 = 4294993638
241 + 4294993397 = 4294993638
311 + 4294993327 = 4294993638
347 + 4294993291 = 4294993638
349 + 4294993289 = 4294993638

Showing the first eight; more decompositions exist.
