Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621894, here are decompositions:

13 + 33621881 = 33621894
37 + 33621857 = 33621894
71 + 33621823 = 33621894
107 + 33621787 = 33621894
113 + 33621781 = 33621894
167 + 33621727 = 33621894
181 + 33621713 = 33621894
233 + 33621661 = 33621894

Showing the first eight; more decompositions exist.
