Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997186, here are decompositions:

23 + 997163 = 997186
83 + 997103 = 997186
89 + 997097 = 997186
149 + 997037 = 997186
167 + 997019 = 997186
173 + 997013 = 997186
233 + 996953 = 997186
383 + 996803 = 997186

Showing the first eight; more decompositions exist.
