Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33547220, here are decompositions:

67 + 33547153 = 33547220
73 + 33547147 = 33547220
103 + 33547117 = 33547220
127 + 33547093 = 33547220
139 + 33547081 = 33547220
163 + 33547057 = 33547220
199 + 33547021 = 33547220
337 + 33546883 = 33547220

Showing the first eight; more decompositions exist.
