Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33511572, here are decompositions:

11 + 33511561 = 33511572
23 + 33511549 = 33511572
41 + 33511531 = 33511572
53 + 33511519 = 33511572
163 + 33511409 = 33511572
173 + 33511399 = 33511572
233 + 33511339 = 33511572
251 + 33511321 = 33511572

Showing the first eight; more decompositions exist.
