Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521790, here are decompositions:

7 + 33521783 = 33521790
31 + 33521759 = 33521790
37 + 33521753 = 33521790
59 + 33521731 = 33521790
61 + 33521729 = 33521790
79 + 33521711 = 33521790
89 + 33521701 = 33521790
97 + 33521693 = 33521790

Showing the first eight; more decompositions exist.
