Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105874, here are decompositions:

3 + 105871 = 105874
11 + 105863 = 105874
107 + 105767 = 105874
113 + 105761 = 105874
173 + 105701 = 105874
191 + 105683 = 105874
311 + 105563 = 105874
317 + 105557 = 105874

Showing the first eight; more decompositions exist.
