Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105884, here are decompositions:

13 + 105871 = 105884
67 + 105817 = 105884
151 + 105733 = 105884
157 + 105727 = 105884
193 + 105691 = 105884
211 + 105673 = 105884
271 + 105613 = 105884
277 + 105607 = 105884

Showing the first eight; more decompositions exist.
