Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505720, here are decompositions:

89 + 33505631 = 33505720
173 + 33505547 = 33505720
317 + 33505403 = 33505720
359 + 33505361 = 33505720
383 + 33505337 = 33505720
419 + 33505301 = 33505720
467 + 33505253 = 33505720
491 + 33505229 = 33505720

Showing the first eight; more decompositions exist.
