Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481820, here are decompositions:

3 + 33481817 = 33481820
13 + 33481807 = 33481820
19 + 33481801 = 33481820
37 + 33481783 = 33481820
61 + 33481759 = 33481820
67 + 33481753 = 33481820
193 + 33481627 = 33481820
223 + 33481597 = 33481820

Showing the first eight; more decompositions exist.
