Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102250, here are decompositions:

17 + 102233 = 102250
47 + 102203 = 102250
53 + 102197 = 102250
59 + 102191 = 102250
89 + 102161 = 102250
101 + 102149 = 102250
149 + 102101 = 102250
173 + 102077 = 102250

Showing the first eight; more decompositions exist.
