Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553188, here are decompositions:

17 + 33553171 = 33553188
37 + 33553151 = 33553188
47 + 33553141 = 33553188
131 + 33553057 = 33553188
139 + 33553049 = 33553188
239 + 33552949 = 33553188
241 + 33552947 = 33553188
359 + 33552829 = 33553188

Showing the first eight; more decompositions exist.
