Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521628, here are decompositions:

5 + 33521623 = 33521628
79 + 33521549 = 33521628
89 + 33521539 = 33521628
97 + 33521531 = 33521628
157 + 33521471 = 33521628
167 + 33521461 = 33521628
191 + 33521437 = 33521628
197 + 33521431 = 33521628

Showing the first eight; more decompositions exist.
