Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553180, here are decompositions:

29 + 33553151 = 33553180
131 + 33553049 = 33553180
179 + 33553001 = 33553180
197 + 33552983 = 33553180
233 + 33552947 = 33553180
257 + 33552923 = 33553180
431 + 33552749 = 33553180
503 + 33552677 = 33553180

Showing the first eight; more decompositions exist.
