Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561504, here are decompositions:

43 + 561461 = 561504
127 + 561377 = 561504
131 + 561373 = 561504
137 + 561367 = 561504
157 + 561347 = 561504
191 + 561313 = 561504
197 + 561307 = 561504
227 + 561277 = 561504

Showing the first eight; more decompositions exist.
