Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997130, here are decompositions:

7 + 997123 = 997130
19 + 997111 = 997130
31 + 997099 = 997130
61 + 997069 = 997130
73 + 997057 = 997130
109 + 997021 = 997130
151 + 996979 = 997130
157 + 996973 = 997130

Showing the first eight; more decompositions exist.
