Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561128, here are decompositions:

19 + 561109 = 561128
31 + 561097 = 561128
37 + 561091 = 561128
67 + 561061 = 561128
109 + 561019 = 561128
151 + 560977 = 561128
199 + 560929 = 561128
241 + 560887 = 561128

Showing the first eight; more decompositions exist.
