Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621628, here are decompositions:

17 + 33621611 = 33621628
137 + 33621491 = 33621628
191 + 33621437 = 33621628
239 + 33621389 = 33621628
317 + 33621311 = 33621628
479 + 33621149 = 33621628
701 + 33620927 = 33621628
809 + 33620819 = 33621628

Showing the first eight; more decompositions exist.
