Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33530138, here are decompositions:

67 + 33530071 = 33530138
79 + 33530059 = 33530138
151 + 33529987 = 33530138
181 + 33529957 = 33530138
277 + 33529861 = 33530138
349 + 33529789 = 33530138
751 + 33529387 = 33530138
769 + 33529369 = 33530138

Showing the first eight; more decompositions exist.
