Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561324, here are decompositions:

11 + 561313 = 561324
17 + 561307 = 561324
47 + 561277 = 561324
73 + 561251 = 561324
151 + 561173 = 561324
163 + 561161 = 561324
223 + 561101 = 561324
227 + 561097 = 561324

Showing the first eight; more decompositions exist.
