Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33563578, here are decompositions:

11 + 33563567 = 33563578
107 + 33563471 = 33563578
131 + 33563447 = 33563578
137 + 33563441 = 33563578
197 + 33563381 = 33563578
239 + 33563339 = 33563578
311 + 33563267 = 33563578
557 + 33563021 = 33563578

Showing the first eight; more decompositions exist.
