Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33474688, here are decompositions:

167 + 33474521 = 33474688
179 + 33474509 = 33474688
227 + 33474461 = 33474688
257 + 33474431 = 33474688
347 + 33474341 = 33474688
491 + 33474197 = 33474688
509 + 33474179 = 33474688
761 + 33473927 = 33474688

Showing the first eight; more decompositions exist.
