Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508820, here are decompositions:

3 + 33508817 = 33508820
13 + 33508807 = 33508820
19 + 33508801 = 33508820
67 + 33508753 = 33508820
181 + 33508639 = 33508820
193 + 33508627 = 33508820
271 + 33508549 = 33508820
313 + 33508507 = 33508820

Showing the first eight; more decompositions exist.
