Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621580, here are decompositions:

89 + 33621491 = 33621580
107 + 33621473 = 33621580
173 + 33621407 = 33621580
191 + 33621389 = 33621580
197 + 33621383 = 33621580
269 + 33621311 = 33621580
281 + 33621299 = 33621580
347 + 33621233 = 33621580

Showing the first eight; more decompositions exist.
