Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997108, here are decompositions:

5 + 997103 = 997108
11 + 997097 = 997108
17 + 997091 = 997108
71 + 997037 = 997108
89 + 997019 = 997108
107 + 997001 = 997108
227 + 996881 = 997108
251 + 996857 = 997108

Showing the first eight; more decompositions exist.
