Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33613638, here are decompositions:

17 + 33613621 = 33613638
41 + 33613597 = 33613638
61 + 33613577 = 33613638
67 + 33613571 = 33613638
89 + 33613549 = 33613638
101 + 33613537 = 33613638
139 + 33613499 = 33613638
181 + 33613457 = 33613638

Showing the first eight; more decompositions exist.
