Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487212, here are decompositions:

19 + 33487193 = 33487212
23 + 33487189 = 33487212
61 + 33487151 = 33487212
131 + 33487081 = 33487212
151 + 33487061 = 33487212
163 + 33487049 = 33487212
179 + 33487033 = 33487212
181 + 33487031 = 33487212

Showing the first eight; more decompositions exist.
