Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561164, here are decompositions:

3 + 33561161 = 33561164
61 + 33561103 = 33561164
97 + 33561067 = 33561164
151 + 33561013 = 33561164
157 + 33561007 = 33561164
181 + 33560983 = 33561164
283 + 33560881 = 33561164
313 + 33560851 = 33561164

Showing the first eight; more decompositions exist.
