Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101166, here are decompositions:

5 + 101161 = 101166
7 + 101159 = 101166
17 + 101149 = 101166
47 + 101119 = 101166
53 + 101113 = 101166
59 + 101107 = 101166
103 + 101063 = 101166
139 + 101027 = 101166

Showing the first eight; more decompositions exist.
