Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561526, here are decompositions:

5 + 561521 = 561526
107 + 561419 = 561526
137 + 561389 = 561526
149 + 561377 = 561526
167 + 561359 = 561526
179 + 561347 = 561526
353 + 561173 = 561526
443 + 561083 = 561526

Showing the first eight; more decompositions exist.
