Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621490, here are decompositions:

17 + 33621473 = 33621490
53 + 33621437 = 33621490
83 + 33621407 = 33621490
101 + 33621389 = 33621490
107 + 33621383 = 33621490
179 + 33621311 = 33621490
191 + 33621299 = 33621490
239 + 33621251 = 33621490

Showing the first eight; more decompositions exist.
