Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997172, here are decompositions:

19 + 997153 = 997172
31 + 997141 = 997172
61 + 997111 = 997172
73 + 997099 = 997172
103 + 997069 = 997172
151 + 997021 = 997172
193 + 996979 = 997172
199 + 996973 = 997172

Showing the first eight; more decompositions exist.
