Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561264, here are decompositions:

13 + 561251 = 561264
73 + 561191 = 561264
83 + 561181 = 561264
103 + 561161 = 561264
163 + 561101 = 561264
167 + 561097 = 561264
173 + 561091 = 561264
181 + 561083 = 561264

Showing the first eight; more decompositions exist.
