Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10858, here are decompositions:

5 + 10853 = 10858
11 + 10847 = 10858
59 + 10799 = 10858
149 + 10709 = 10858
167 + 10691 = 10858
191 + 10667 = 10858
227 + 10631 = 10858
251 + 10607 = 10858

Showing the first eight; more decompositions exist.
