Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561552, here are decompositions:

23 + 561529 = 561552
31 + 561521 = 561552
113 + 561439 = 561552
163 + 561389 = 561552
179 + 561373 = 561552
193 + 561359 = 561552
239 + 561313 = 561552
353 + 561199 = 561552

Showing the first eight; more decompositions exist.
