Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621960, here are decompositions:

37 + 33621923 = 33621960
59 + 33621901 = 33621960
79 + 33621881 = 33621960
101 + 33621859 = 33621960
103 + 33621857 = 33621960
137 + 33621823 = 33621960
173 + 33621787 = 33621960
179 + 33621781 = 33621960

Showing the first eight; more decompositions exist.
