Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 563666, here are decompositions:

3 + 563663 = 563666
43 + 563623 = 563666
67 + 563599 = 563666
73 + 563593 = 563666
79 + 563587 = 563666
163 + 563503 = 563666
199 + 563467 = 563666
307 + 563359 = 563666

Showing the first eight; more decompositions exist.
