Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553372, here are decompositions:

3 + 33553369 = 33553372
59 + 33553313 = 33553372
71 + 33553301 = 33553372
89 + 33553283 = 33553372
101 + 33553271 = 33553372
179 + 33553193 = 33553372
269 + 33553103 = 33553372
389 + 33552983 = 33553372

Showing the first eight; more decompositions exist.
