Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621144, here are decompositions:

31 + 33621113 = 33621144
61 + 33621083 = 33621144
97 + 33621047 = 33621144
107 + 33621037 = 33621144
113 + 33621031 = 33621144
233 + 33620911 = 33621144
331 + 33620813 = 33621144
383 + 33620761 = 33621144

Showing the first eight; more decompositions exist.
