Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10258, here are decompositions:

5 + 10253 = 10258
11 + 10247 = 10258
47 + 10211 = 10258
89 + 10169 = 10258
107 + 10151 = 10258
167 + 10091 = 10258
179 + 10079 = 10258
191 + 10067 = 10258

Showing the first eight; more decompositions exist.
