Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56638, here are decompositions:

5 + 56633 = 56638
41 + 56597 = 56638
47 + 56591 = 56638
107 + 56531 = 56638
137 + 56501 = 56638
149 + 56489 = 56638
269 + 56369 = 56638
389 + 56249 = 56638

Showing the first eight; more decompositions exist.
