Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33612880, here are decompositions:

3 + 33612877 = 33612880
11 + 33612869 = 33612880
83 + 33612797 = 33612880
173 + 33612707 = 33612880
179 + 33612701 = 33612880
269 + 33612611 = 33612880
347 + 33612533 = 33612880
443 + 33612437 = 33612880

Showing the first eight; more decompositions exist.
