Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621412, here are decompositions:

3 + 33621409 = 33621412
5 + 33621407 = 33621412
23 + 33621389 = 33621412
29 + 33621383 = 33621412
101 + 33621311 = 33621412
113 + 33621299 = 33621412
179 + 33621233 = 33621412
239 + 33621173 = 33621412

Showing the first eight; more decompositions exist.
