Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33547180, here are decompositions:

11 + 33547169 = 33547180
41 + 33547139 = 33547180
71 + 33547109 = 33547180
83 + 33547097 = 33547180
137 + 33547043 = 33547180
167 + 33547013 = 33547180
239 + 33546941 = 33547180
263 + 33546917 = 33547180

Showing the first eight; more decompositions exist.
