Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531988, here are decompositions:

11 + 33531977 = 33531988
41 + 33531947 = 33531988
59 + 33531929 = 33531988
101 + 33531887 = 33531988
197 + 33531791 = 33531988
239 + 33531749 = 33531988
251 + 33531737 = 33531988
317 + 33531671 = 33531988

Showing the first eight; more decompositions exist.
