Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521980, here are decompositions:

47 + 33521933 = 33521980
53 + 33521927 = 33521980
59 + 33521921 = 33521980
137 + 33521843 = 33521980
197 + 33521783 = 33521980
227 + 33521753 = 33521980
251 + 33521729 = 33521980
269 + 33521711 = 33521980

Showing the first eight; more decompositions exist.
