Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78258, here are decompositions:

17 + 78241 = 78258
29 + 78229 = 78258
67 + 78191 = 78258
79 + 78179 = 78258
101 + 78157 = 78258
137 + 78121 = 78258
157 + 78101 = 78258
179 + 78079 = 78258

Showing the first eight; more decompositions exist.
