Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33471728, here are decompositions:

7 + 33471721 = 33471728
19 + 33471709 = 33471728
61 + 33471667 = 33471728
79 + 33471649 = 33471728
151 + 33471577 = 33471728
181 + 33471547 = 33471728
331 + 33471397 = 33471728
457 + 33471271 = 33471728

Showing the first eight; more decompositions exist.
