Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102108, here are decompositions:

5 + 102103 = 102108
7 + 102101 = 102108
29 + 102079 = 102108
31 + 102077 = 102108
37 + 102071 = 102108
47 + 102061 = 102108
89 + 102019 = 102108
107 + 102001 = 102108

Showing the first eight; more decompositions exist.
