Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33498180, here are decompositions:

41 + 33498139 = 33498180
61 + 33498119 = 33498180
109 + 33498071 = 33498180
137 + 33498043 = 33498180
181 + 33497999 = 33498180
197 + 33497983 = 33498180
227 + 33497953 = 33498180
229 + 33497951 = 33498180

Showing the first eight; more decompositions exist.
