Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105068, here are decompositions:

31 + 105037 = 105068
37 + 105031 = 105068
97 + 104971 = 105068
109 + 104959 = 105068
151 + 104917 = 105068
157 + 104911 = 105068
199 + 104869 = 105068
241 + 104827 = 105068

Showing the first eight; more decompositions exist.
