Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508180, here are decompositions:

53 + 33508127 = 33508180
71 + 33508109 = 33508180
89 + 33508091 = 33508180
113 + 33508067 = 33508180
137 + 33508043 = 33508180
191 + 33507989 = 33508180
257 + 33507923 = 33508180
269 + 33507911 = 33508180

Showing the first eight; more decompositions exist.
