Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561084, here are decompositions:

5 + 561079 = 561084
23 + 561061 = 561084
31 + 561053 = 561084
37 + 561047 = 561084
107 + 560977 = 561084
191 + 560893 = 561084
193 + 560891 = 561084
197 + 560887 = 561084

Showing the first eight; more decompositions exist.
