Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33471980, here are decompositions:

7 + 33471973 = 33471980
127 + 33471853 = 33471980
181 + 33471799 = 33471980
211 + 33471769 = 33471980
271 + 33471709 = 33471980
313 + 33471667 = 33471980
331 + 33471649 = 33471980
397 + 33471583 = 33471980

Showing the first eight; more decompositions exist.
