Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621818, here are decompositions:

31 + 33621787 = 33621818
37 + 33621781 = 33621818
67 + 33621751 = 33621818
127 + 33621691 = 33621818
157 + 33621661 = 33621818
277 + 33621541 = 33621818
409 + 33621409 = 33621818
421 + 33621397 = 33621818

Showing the first eight; more decompositions exist.
