Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521042, here are decompositions:

3 + 33521039 = 33521042
103 + 33520939 = 33521042
151 + 33520891 = 33521042
199 + 33520843 = 33521042
229 + 33520813 = 33521042
241 + 33520801 = 33521042
283 + 33520759 = 33521042
421 + 33520621 = 33521042

Showing the first eight; more decompositions exist.
