Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561252, here are decompositions:

23 + 561229 = 561252
53 + 561199 = 561252
61 + 561191 = 561252
71 + 561181 = 561252
79 + 561173 = 561252
149 + 561103 = 561252
151 + 561101 = 561252
173 + 561079 = 561252

Showing the first eight; more decompositions exist.
