Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621390, here are decompositions:

7 + 33621383 = 33621390
29 + 33621361 = 33621390
79 + 33621311 = 33621390
107 + 33621283 = 33621390
137 + 33621253 = 33621390
139 + 33621251 = 33621390
157 + 33621233 = 33621390
227 + 33621163 = 33621390

Showing the first eight; more decompositions exist.
