Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521788, here are decompositions:

5 + 33521783 = 33521788
29 + 33521759 = 33521788
59 + 33521729 = 33521788
239 + 33521549 = 33521788
257 + 33521531 = 33521788
317 + 33521471 = 33521788
467 + 33521321 = 33521788
569 + 33521219 = 33521788

Showing the first eight; more decompositions exist.
