Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33522640, here are decompositions:

59 + 33522581 = 33522640
131 + 33522509 = 33522640
191 + 33522449 = 33522640
251 + 33522389 = 33522640
269 + 33522371 = 33522640
401 + 33522239 = 33522640
443 + 33522197 = 33522640
461 + 33522179 = 33522640

Showing the first eight; more decompositions exist.
