Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621312, here are decompositions:

13 + 33621299 = 33621312
29 + 33621283 = 33621312
59 + 33621253 = 33621312
61 + 33621251 = 33621312
79 + 33621233 = 33621312
139 + 33621173 = 33621312
149 + 33621163 = 33621312
163 + 33621149 = 33621312

Showing the first eight; more decompositions exist.
