Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294994638, here are decompositions:

149 + 4294994489 = 4294994638
239 + 4294994399 = 4294994638
251 + 4294994387 = 4294994638
281 + 4294994357 = 4294994638
479 + 4294994159 = 4294994638
521 + 4294994117 = 4294994638
659 + 4294993979 = 4294994638
677 + 4294993961 = 4294994638

Showing the first eight; more decompositions exist.
