Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521146, here are decompositions:

5 + 33521141 = 33521146
47 + 33521099 = 33521146
59 + 33521087 = 33521146
89 + 33521057 = 33521146
107 + 33521039 = 33521146
137 + 33521009 = 33521146
167 + 33520979 = 33521146
173 + 33520973 = 33521146

Showing the first eight; more decompositions exist.
