Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481680, here are decompositions:

53 + 33481627 = 33481680
83 + 33481597 = 33481680
103 + 33481577 = 33481680
109 + 33481571 = 33481680
131 + 33481549 = 33481680
173 + 33481507 = 33481680
181 + 33481499 = 33481680
251 + 33481429 = 33481680

Showing the first eight; more decompositions exist.
