Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481790, here are decompositions:

7 + 33481783 = 33481790
31 + 33481759 = 33481790
37 + 33481753 = 33481790
61 + 33481729 = 33481790
163 + 33481627 = 33481790
193 + 33481597 = 33481790
241 + 33481549 = 33481790
283 + 33481507 = 33481790

Showing the first eight; more decompositions exist.
