Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531646, here are decompositions:

59 + 33531587 = 33531646
167 + 33531479 = 33531646
173 + 33531473 = 33531646
179 + 33531467 = 33531646
233 + 33531413 = 33531646
257 + 33531389 = 33531646
293 + 33531353 = 33531646
347 + 33531299 = 33531646

Showing the first eight; more decompositions exist.
