Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 53638, here are decompositions:

5 + 53633 = 53638
29 + 53609 = 53638
41 + 53597 = 53638
47 + 53591 = 53638
89 + 53549 = 53638
131 + 53507 = 53638
197 + 53441 = 53638
227 + 53411 = 53638

Showing the first eight; more decompositions exist.
