Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33608180, here are decompositions:

37 + 33608143 = 33608180
211 + 33607969 = 33608180
223 + 33607957 = 33608180
271 + 33607909 = 33608180
337 + 33607843 = 33608180
349 + 33607831 = 33608180
379 + 33607801 = 33608180
409 + 33607771 = 33608180

Showing the first eight; more decompositions exist.
