Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33530180, here are decompositions:

109 + 33530071 = 33530180
157 + 33530023 = 33530180
193 + 33529987 = 33530180
223 + 33529957 = 33530180
433 + 33529747 = 33530180
571 + 33529609 = 33530180
577 + 33529603 = 33530180
811 + 33529369 = 33530180

Showing the first eight; more decompositions exist.
