Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553390, here are decompositions:

11 + 33553379 = 33553390
53 + 33553337 = 33553390
83 + 33553307 = 33553390
89 + 33553301 = 33553390
107 + 33553283 = 33553390
197 + 33553193 = 33553390
239 + 33553151 = 33553390
389 + 33553001 = 33553390

Showing the first eight; more decompositions exist.
