Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561108, here are decompositions:

5 + 561103 = 561108
7 + 561101 = 561108
11 + 561097 = 561108
17 + 561091 = 561108
29 + 561079 = 561108
47 + 561061 = 561108
61 + 561047 = 561108
89 + 561019 = 561108

Showing the first eight; more decompositions exist.
