Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 563628, here are decompositions:

5 + 563623 = 563628
29 + 563599 = 563628
41 + 563587 = 563628
67 + 563561 = 563628
127 + 563501 = 563628
139 + 563489 = 563628
179 + 563449 = 563628
181 + 563447 = 563628

Showing the first eight; more decompositions exist.
