Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997180, here are decompositions:

17 + 997163 = 997180
29 + 997151 = 997180
59 + 997121 = 997180
71 + 997109 = 997180
83 + 997097 = 997180
89 + 997091 = 997180
137 + 997043 = 997180
167 + 997013 = 997180

Showing the first eight; more decompositions exist.
