Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33591988, here are decompositions:

11 + 33591977 = 33591988
29 + 33591959 = 33591988
71 + 33591917 = 33591988
149 + 33591839 = 33591988
251 + 33591737 = 33591988
347 + 33591641 = 33591988
359 + 33591629 = 33591988
461 + 33591527 = 33591988

Showing the first eight; more decompositions exist.
