Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621616, here are decompositions:

5 + 33621611 = 33621616
23 + 33621593 = 33621616
179 + 33621437 = 33621616
227 + 33621389 = 33621616
233 + 33621383 = 33621616
317 + 33621299 = 33621616
383 + 33621233 = 33621616
443 + 33621173 = 33621616

Showing the first eight; more decompositions exist.
