Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621328, here are decompositions:

17 + 33621311 = 33621328
29 + 33621299 = 33621328
179 + 33621149 = 33621328
281 + 33621047 = 33621328
401 + 33620927 = 33621328
509 + 33620819 = 33621328
647 + 33620681 = 33621328
701 + 33620627 = 33621328

Showing the first eight; more decompositions exist.
