Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561206, here are decompositions:

7 + 561199 = 561206
97 + 561109 = 561206
103 + 561103 = 561206
109 + 561097 = 561206
127 + 561079 = 561206
229 + 560977 = 561206
277 + 560929 = 561206
313 + 560893 = 561206

Showing the first eight; more decompositions exist.
