Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102216, here are decompositions:

13 + 102203 = 102216
17 + 102199 = 102216
19 + 102197 = 102216
67 + 102149 = 102216
109 + 102107 = 102216
113 + 102103 = 102216
137 + 102079 = 102216
139 + 102077 = 102216

Showing the first eight; more decompositions exist.
