Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621426, here are decompositions:

17 + 33621409 = 33621426
19 + 33621407 = 33621426
29 + 33621397 = 33621426
37 + 33621389 = 33621426
43 + 33621383 = 33621426
127 + 33621299 = 33621426
173 + 33621253 = 33621426
193 + 33621233 = 33621426

Showing the first eight; more decompositions exist.
