Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102262, here are decompositions:

3 + 102259 = 102262
11 + 102251 = 102262
29 + 102233 = 102262
59 + 102203 = 102262
71 + 102191 = 102262
101 + 102161 = 102262
113 + 102149 = 102262
191 + 102071 = 102262

Showing the first eight; more decompositions exist.
