Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47638, here are decompositions:

29 + 47609 = 47638
47 + 47591 = 47638
131 + 47507 = 47638
137 + 47501 = 47638
179 + 47459 = 47638
197 + 47441 = 47638
251 + 47387 = 47638
257 + 47381 = 47638

Showing the first eight; more decompositions exist.
