Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997166, here are decompositions:

3 + 997163 = 997166
13 + 997153 = 997166
19 + 997147 = 997166
43 + 997123 = 997166
67 + 997099 = 997166
97 + 997069 = 997166
109 + 997057 = 997166
193 + 996973 = 997166

Showing the first eight; more decompositions exist.
