Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102156, here are decompositions:

7 + 102149 = 102156
17 + 102139 = 102156
53 + 102103 = 102156
79 + 102077 = 102156
97 + 102059 = 102156
113 + 102043 = 102156
137 + 102019 = 102156
157 + 101999 = 102156

Showing the first eight; more decompositions exist.
