Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621990, here are decompositions:

67 + 33621923 = 33621990
79 + 33621911 = 33621990
89 + 33621901 = 33621990
109 + 33621881 = 33621990
131 + 33621859 = 33621990
151 + 33621839 = 33621990
167 + 33621823 = 33621990
229 + 33621761 = 33621990

Showing the first eight; more decompositions exist.
