Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621544, here are decompositions:

3 + 33621541 = 33621544
53 + 33621491 = 33621544
71 + 33621473 = 33621544
107 + 33621437 = 33621544
137 + 33621407 = 33621544
233 + 33621311 = 33621544
293 + 33621251 = 33621544
311 + 33621233 = 33621544

Showing the first eight; more decompositions exist.
