Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561258, here are decompositions:

7 + 561251 = 561258
29 + 561229 = 561258
59 + 561199 = 561258
67 + 561191 = 561258
97 + 561161 = 561258
149 + 561109 = 561258
157 + 561101 = 561258
167 + 561091 = 561258

Showing the first eight; more decompositions exist.
