Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105958, here are decompositions:

5 + 105953 = 105958
29 + 105929 = 105958
59 + 105899 = 105958
191 + 105767 = 105958
197 + 105761 = 105958
257 + 105701 = 105958
401 + 105557 = 105958
431 + 105527 = 105958

Showing the first eight; more decompositions exist.
