Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553290, here are decompositions:

7 + 33553283 = 33553290
19 + 33553271 = 33553290
97 + 33553193 = 33553290
137 + 33553153 = 33553290
139 + 33553151 = 33553290
149 + 33553141 = 33553290
233 + 33553057 = 33553290
241 + 33553049 = 33553290

Showing the first eight; more decompositions exist.
