Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621380, here are decompositions:

19 + 33621361 = 33621380
97 + 33621283 = 33621380
127 + 33621253 = 33621380
211 + 33621169 = 33621380
271 + 33621109 = 33621380
313 + 33621067 = 33621380
349 + 33621031 = 33621380
421 + 33620959 = 33621380

Showing the first eight; more decompositions exist.
