Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561310, here are decompositions:

3 + 561307 = 561310
59 + 561251 = 561310
137 + 561173 = 561310
149 + 561161 = 561310
227 + 561083 = 561310
251 + 561059 = 561310
257 + 561053 = 561310
263 + 561047 = 561310

Showing the first eight; more decompositions exist.
