Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553420, here are decompositions:

3 + 33553417 = 33553420
41 + 33553379 = 33553420
83 + 33553337 = 33553420
107 + 33553313 = 33553420
113 + 33553307 = 33553420
137 + 33553283 = 33553420
149 + 33553271 = 33553420
227 + 33553193 = 33553420

Showing the first eight; more decompositions exist.
