Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621930, here are decompositions:

7 + 33621923 = 33621930
19 + 33621911 = 33621930
29 + 33621901 = 33621930
71 + 33621859 = 33621930
73 + 33621857 = 33621930
107 + 33621823 = 33621930
149 + 33621781 = 33621930
179 + 33621751 = 33621930

Showing the first eight; more decompositions exist.
