Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621558, here are decompositions:

17 + 33621541 = 33621558
67 + 33621491 = 33621558
149 + 33621409 = 33621558
151 + 33621407 = 33621558
197 + 33621361 = 33621558
307 + 33621251 = 33621558
389 + 33621169 = 33621558
409 + 33621149 = 33621558

Showing the first eight; more decompositions exist.
