Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561228, here are decompositions:

29 + 561199 = 561228
37 + 561191 = 561228
47 + 561181 = 561228
67 + 561161 = 561228
127 + 561101 = 561228
131 + 561097 = 561228
137 + 561091 = 561228
149 + 561079 = 561228

Showing the first eight; more decompositions exist.
