Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621372, here are decompositions:

11 + 33621361 = 33621372
61 + 33621311 = 33621372
73 + 33621299 = 33621372
89 + 33621283 = 33621372
139 + 33621233 = 33621372
199 + 33621173 = 33621372
223 + 33621149 = 33621372
263 + 33621109 = 33621372

Showing the first eight; more decompositions exist.
