Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63638, here are decompositions:

31 + 63607 = 63638
37 + 63601 = 63638
61 + 63577 = 63638
79 + 63559 = 63638
97 + 63541 = 63638
139 + 63499 = 63638
151 + 63487 = 63638
199 + 63439 = 63638

Showing the first eight; more decompositions exist.
