Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33613220, here are decompositions:

7 + 33613213 = 33613220
139 + 33613081 = 33613220
181 + 33613039 = 33613220
211 + 33613009 = 33613220
229 + 33612991 = 33613220
241 + 33612979 = 33613220
367 + 33612853 = 33613220
397 + 33612823 = 33613220

Showing the first eight; more decompositions exist.
