Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621638, here are decompositions:

79 + 33621559 = 33621638
97 + 33621541 = 33621638
229 + 33621409 = 33621638
241 + 33621397 = 33621638
277 + 33621361 = 33621638
571 + 33621067 = 33621638
601 + 33621037 = 33621638
607 + 33621031 = 33621638

Showing the first eight; more decompositions exist.
