Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33566178, here are decompositions:

71 + 33566107 = 33566178
109 + 33566069 = 33566178
167 + 33566011 = 33566178
181 + 33565997 = 33566178
211 + 33565967 = 33566178
241 + 33565937 = 33566178
337 + 33565841 = 33566178
367 + 33565811 = 33566178

Showing the first eight; more decompositions exist.
