Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33530168, here are decompositions:

97 + 33530071 = 33530168
109 + 33530059 = 33530168
181 + 33529987 = 33530168
211 + 33529957 = 33530168
307 + 33529861 = 33530168
349 + 33529819 = 33530168
379 + 33529789 = 33530168
421 + 33529747 = 33530168

Showing the first eight; more decompositions exist.
