Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521538, here are decompositions:

7 + 33521531 = 33521538
67 + 33521471 = 33521538
101 + 33521437 = 33521538
107 + 33521431 = 33521538
137 + 33521401 = 33521538
317 + 33521221 = 33521538
359 + 33521179 = 33521538
367 + 33521171 = 33521538

Showing the first eight; more decompositions exist.
