Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621442, here are decompositions:

5 + 33621437 = 33621442
53 + 33621389 = 33621442
59 + 33621383 = 33621442
131 + 33621311 = 33621442
191 + 33621251 = 33621442
269 + 33621173 = 33621442
293 + 33621149 = 33621442
359 + 33621083 = 33621442

Showing the first eight; more decompositions exist.
