Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621908, here are decompositions:

7 + 33621901 = 33621908
127 + 33621781 = 33621908
157 + 33621751 = 33621908
181 + 33621727 = 33621908
349 + 33621559 = 33621908
367 + 33621541 = 33621908
499 + 33621409 = 33621908
547 + 33621361 = 33621908

Showing the first eight; more decompositions exist.
