Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 563646, here are decompositions:

23 + 563623 = 563646
47 + 563599 = 563646
53 + 563593 = 563646
59 + 563587 = 563646
103 + 563543 = 563646
157 + 563489 = 563646
179 + 563467 = 563646
197 + 563449 = 563646

Showing the first eight; more decompositions exist.
