Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105066, here are decompositions:

29 + 105037 = 105066
43 + 105023 = 105066
47 + 105019 = 105066
67 + 104999 = 105066
79 + 104987 = 105066
107 + 104959 = 105066
113 + 104953 = 105066
149 + 104917 = 105066

Showing the first eight; more decompositions exist.
