Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621770, here are decompositions:

19 + 33621751 = 33621770
43 + 33621727 = 33621770
79 + 33621691 = 33621770
97 + 33621673 = 33621770
109 + 33621661 = 33621770
211 + 33621559 = 33621770
229 + 33621541 = 33621770
373 + 33621397 = 33621770

Showing the first eight; more decompositions exist.
