Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553218, here are decompositions:

47 + 33553171 = 33553218
67 + 33553151 = 33553218
191 + 33553027 = 33553218
269 + 33552949 = 33553218
271 + 33552947 = 33553218
359 + 33552859 = 33553218
389 + 33552829 = 33553218
409 + 33552809 = 33553218

Showing the first eight; more decompositions exist.
