Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521672, here are decompositions:

43 + 33521629 = 33521672
211 + 33521461 = 33521672
241 + 33521431 = 33521672
271 + 33521401 = 33521672
733 + 33520939 = 33521672
829 + 33520843 = 33521672
859 + 33520813 = 33521672
991 + 33520681 = 33521672

Showing the first eight; more decompositions exist.
