Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505642, here are decompositions:

11 + 33505631 = 33505642
41 + 33505601 = 33505642
239 + 33505403 = 33505642
281 + 33505361 = 33505642
389 + 33505253 = 33505642
431 + 33505211 = 33505642
479 + 33505163 = 33505642
593 + 33505049 = 33505642

Showing the first eight; more decompositions exist.
