Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561534, here are decompositions:

5 + 561529 = 561534
13 + 561521 = 561534
73 + 561461 = 561534
157 + 561377 = 561534
167 + 561367 = 561534
191 + 561343 = 561534
227 + 561307 = 561534
257 + 561277 = 561534

Showing the first eight; more decompositions exist.
