Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561212, here are decompositions:

13 + 561199 = 561212
31 + 561181 = 561212
103 + 561109 = 561212
109 + 561103 = 561212
151 + 561061 = 561212
193 + 561019 = 561212
271 + 560941 = 561212
283 + 560929 = 561212

Showing the first eight; more decompositions exist.
