Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481788, here are decompositions:

5 + 33481783 = 33481788
19 + 33481769 = 33481788
29 + 33481759 = 33481788
31 + 33481757 = 33481788
37 + 33481751 = 33481788
59 + 33481729 = 33481788
191 + 33481597 = 33481788
211 + 33481577 = 33481788

Showing the first eight; more decompositions exist.
