Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33533578, here are decompositions:

131 + 33533447 = 33533578
191 + 33533387 = 33533578
257 + 33533321 = 33533578
311 + 33533267 = 33533578
317 + 33533261 = 33533578
557 + 33533021 = 33533578
647 + 33532931 = 33533578
761 + 33532817 = 33533578

Showing the first eight; more decompositions exist.
