Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621900, here are decompositions:

19 + 33621881 = 33621900
41 + 33621859 = 33621900
43 + 33621857 = 33621900
61 + 33621839 = 33621900
113 + 33621787 = 33621900
139 + 33621761 = 33621900
149 + 33621751 = 33621900
173 + 33621727 = 33621900

Showing the first eight; more decompositions exist.
