Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102138, here are decompositions:

17 + 102121 = 102138
31 + 102107 = 102138
37 + 102101 = 102138
59 + 102079 = 102138
61 + 102077 = 102138
67 + 102071 = 102138
79 + 102059 = 102138
107 + 102031 = 102138

Showing the first eight; more decompositions exist.
