Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561344, here are decompositions:

31 + 561313 = 561344
37 + 561307 = 561344
67 + 561277 = 561344
163 + 561181 = 561344
241 + 561103 = 561344
283 + 561061 = 561344
367 + 560977 = 561344
457 + 560887 = 561344

Showing the first eight; more decompositions exist.
