Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578980, here are decompositions:

3 + 33578977 = 33578980
11 + 33578969 = 33578980
47 + 33578933 = 33578980
89 + 33578891 = 33578980
101 + 33578879 = 33578980
173 + 33578807 = 33578980
233 + 33578747 = 33578980
293 + 33578687 = 33578980

Showing the first eight; more decompositions exist.
