Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561276, here are decompositions:

47 + 561229 = 561276
103 + 561173 = 561276
167 + 561109 = 561276
173 + 561103 = 561276
179 + 561097 = 561276
193 + 561083 = 561276
197 + 561079 = 561276
223 + 561053 = 561276

Showing the first eight; more decompositions exist.
