Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105894, here are decompositions:

11 + 105883 = 105894
23 + 105871 = 105894
31 + 105863 = 105894
127 + 105767 = 105894
167 + 105727 = 105894
193 + 105701 = 105894
211 + 105683 = 105894
227 + 105667 = 105894

Showing the first eight; more decompositions exist.
