Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561168, here are decompositions:

7 + 561161 = 561168
59 + 561109 = 561168
67 + 561101 = 561168
71 + 561097 = 561168
89 + 561079 = 561168
107 + 561061 = 561168
109 + 561059 = 561168
149 + 561019 = 561168

Showing the first eight; more decompositions exist.
