Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972166, here are decompositions:

3 + 972163 = 972166
5 + 972161 = 972166
29 + 972137 = 972166
47 + 972119 = 972166
53 + 972113 = 972166
137 + 972029 = 972166
149 + 972017 = 972166
227 + 971939 = 972166

Showing the first eight; more decompositions exist.
