Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621666, here are decompositions:

5 + 33621661 = 33621666
17 + 33621649 = 33621666
37 + 33621629 = 33621666
73 + 33621593 = 33621666
107 + 33621559 = 33621666
193 + 33621473 = 33621666
229 + 33621437 = 33621666
257 + 33621409 = 33621666

Showing the first eight; more decompositions exist.
