Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621420, here are decompositions:

11 + 33621409 = 33621420
13 + 33621407 = 33621420
23 + 33621397 = 33621420
31 + 33621389 = 33621420
37 + 33621383 = 33621420
59 + 33621361 = 33621420
109 + 33621311 = 33621420
137 + 33621283 = 33621420

Showing the first eight; more decompositions exist.
