Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621966, here are decompositions:

43 + 33621923 = 33621966
107 + 33621859 = 33621966
109 + 33621857 = 33621966
127 + 33621839 = 33621966
179 + 33621787 = 33621966
239 + 33621727 = 33621966
293 + 33621673 = 33621966
317 + 33621649 = 33621966

Showing the first eight; more decompositions exist.
