Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521550, here are decompositions:

11 + 33521539 = 33521550
19 + 33521531 = 33521550
67 + 33521483 = 33521550
79 + 33521471 = 33521550
89 + 33521461 = 33521550
113 + 33521437 = 33521550
149 + 33521401 = 33521550
157 + 33521393 = 33521550

Showing the first eight; more decompositions exist.
