Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105658, here are decompositions:

5 + 105653 = 105658
101 + 105557 = 105658
131 + 105527 = 105658
149 + 105509 = 105658
167 + 105491 = 105658
191 + 105467 = 105658
251 + 105407 = 105658
257 + 105401 = 105658

Showing the first eight; more decompositions exist.
