Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105908, here are decompositions:

37 + 105871 = 105908
79 + 105829 = 105908
139 + 105769 = 105908
157 + 105751 = 105908
181 + 105727 = 105908
241 + 105667 = 105908
307 + 105601 = 105908
367 + 105541 = 105908

Showing the first eight; more decompositions exist.
