Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561306, here are decompositions:

29 + 561277 = 561306
107 + 561199 = 561306
197 + 561109 = 561306
223 + 561083 = 561306
227 + 561079 = 561306
337 + 560969 = 561306
367 + 560939 = 561306
409 + 560897 = 561306

Showing the first eight; more decompositions exist.
