Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105168, here are decompositions:

31 + 105137 = 105168
61 + 105107 = 105168
71 + 105097 = 105168
97 + 105071 = 105168
131 + 105037 = 105168
137 + 105031 = 105168
149 + 105019 = 105168
181 + 104987 = 105168

Showing the first eight; more decompositions exist.
