Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521842, here are decompositions:

59 + 33521783 = 33521842
83 + 33521759 = 33521842
89 + 33521753 = 33521842
113 + 33521729 = 33521842
131 + 33521711 = 33521842
149 + 33521693 = 33521842
293 + 33521549 = 33521842
311 + 33521531 = 33521842

Showing the first eight; more decompositions exist.
