Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521930, here are decompositions:

3 + 33521927 = 33521930
37 + 33521893 = 33521930
67 + 33521863 = 33521930
103 + 33521827 = 33521930
109 + 33521821 = 33521930
199 + 33521731 = 33521930
229 + 33521701 = 33521930
241 + 33521689 = 33521930

Showing the first eight; more decompositions exist.
