Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621668, here are decompositions:

7 + 33621661 = 33621668
19 + 33621649 = 33621668
109 + 33621559 = 33621668
127 + 33621541 = 33621668
271 + 33621397 = 33621668
307 + 33621361 = 33621668
499 + 33621169 = 33621668
601 + 33621067 = 33621668

Showing the first eight; more decompositions exist.
