Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102154, here are decompositions:

5 + 102149 = 102154
47 + 102107 = 102154
53 + 102101 = 102154
83 + 102071 = 102154
131 + 102023 = 102154
167 + 101987 = 102154
191 + 101963 = 102154
197 + 101957 = 102154

Showing the first eight; more decompositions exist.
