Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521142, here are decompositions:

43 + 33521099 = 33521142
59 + 33521083 = 33521142
103 + 33521039 = 33521142
139 + 33521003 = 33521142
163 + 33520979 = 33521142
223 + 33520919 = 33521142
251 + 33520891 = 33521142
283 + 33520859 = 33521142

Showing the first eight; more decompositions exist.
