Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105186, here are decompositions:

13 + 105173 = 105186
19 + 105167 = 105186
43 + 105143 = 105186
79 + 105107 = 105186
89 + 105097 = 105186
149 + 105037 = 105186
163 + 105023 = 105186
167 + 105019 = 105186

Showing the first eight; more decompositions exist.
