Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621918, here are decompositions:

7 + 33621911 = 33621918
17 + 33621901 = 33621918
37 + 33621881 = 33621918
59 + 33621859 = 33621918
61 + 33621857 = 33621918
79 + 33621839 = 33621918
131 + 33621787 = 33621918
137 + 33621781 = 33621918

Showing the first eight; more decompositions exist.
