Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521574, here are decompositions:

43 + 33521531 = 33521574
103 + 33521471 = 33521574
113 + 33521461 = 33521574
137 + 33521437 = 33521574
157 + 33521417 = 33521574
173 + 33521401 = 33521574
181 + 33521393 = 33521574
337 + 33521237 = 33521574

Showing the first eight; more decompositions exist.
