Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33532180, here are decompositions:

41 + 33532139 = 33532180
107 + 33532073 = 33532180
113 + 33532067 = 33532180
191 + 33531989 = 33532180
233 + 33531947 = 33532180
251 + 33531929 = 33532180
257 + 33531923 = 33532180
293 + 33531887 = 33532180

Showing the first eight; more decompositions exist.
