Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105948, here are decompositions:

5 + 105943 = 105948
19 + 105929 = 105948
41 + 105907 = 105948
131 + 105817 = 105948
179 + 105769 = 105948
181 + 105767 = 105948
197 + 105751 = 105948
257 + 105691 = 105948

Showing the first eight; more decompositions exist.
