Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621376, here are decompositions:

227 + 33621149 = 33621376
263 + 33621113 = 33621376
293 + 33621083 = 33621376
449 + 33620927 = 33621376
557 + 33620819 = 33621376
563 + 33620813 = 33621376
587 + 33620789 = 33621376
797 + 33620579 = 33621376

Showing the first eight; more decompositions exist.
