Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621138, here are decompositions:

29 + 33621109 = 33621138
71 + 33621067 = 33621138
101 + 33621037 = 33621138
107 + 33621031 = 33621138
139 + 33620999 = 33621138
179 + 33620959 = 33621138
211 + 33620927 = 33621138
227 + 33620911 = 33621138

Showing the first eight; more decompositions exist.
