Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561222, here are decompositions:

23 + 561199 = 561222
31 + 561191 = 561222
41 + 561181 = 561222
61 + 561161 = 561222
113 + 561109 = 561222
131 + 561091 = 561222
139 + 561083 = 561222
163 + 561059 = 561222

Showing the first eight; more decompositions exist.
