Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5638, here are decompositions:

47 + 5591 = 5638
107 + 5531 = 5638
131 + 5507 = 5638
137 + 5501 = 5638
167 + 5471 = 5638
197 + 5441 = 5638
239 + 5399 = 5638
251 + 5387 = 5638

Showing the first eight; more decompositions exist.
