Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102172, here are decompositions:

11 + 102161 = 102172
23 + 102149 = 102172
71 + 102101 = 102172
101 + 102071 = 102172
113 + 102059 = 102172
149 + 102023 = 102172
173 + 101999 = 102172
233 + 101939 = 102172

Showing the first eight; more decompositions exist.
