Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531688, here are decompositions:

17 + 33531671 = 33531688
101 + 33531587 = 33531688
257 + 33531431 = 33531688
389 + 33531299 = 33531688
419 + 33531269 = 33531688
521 + 33531167 = 33531688
677 + 33531011 = 33531688
719 + 33530969 = 33531688

Showing the first eight; more decompositions exist.
