Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123108, here are decompositions:

17 + 123091 = 123108
31 + 123077 = 123108
59 + 123049 = 123108
101 + 123007 = 123108
107 + 123001 = 123108
137 + 122971 = 123108
151 + 122957 = 123108
179 + 122929 = 123108

Showing the first eight; more decompositions exist.
