Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102258, here are decompositions:

5 + 102253 = 102258
7 + 102251 = 102258
17 + 102241 = 102258
29 + 102229 = 102258
41 + 102217 = 102258
59 + 102199 = 102258
61 + 102197 = 102258
67 + 102191 = 102258

Showing the first eight; more decompositions exist.
