Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997184, here are decompositions:

31 + 997153 = 997184
37 + 997147 = 997184
43 + 997141 = 997184
61 + 997123 = 997184
73 + 997111 = 997184
103 + 997081 = 997184
127 + 997057 = 997184
163 + 997021 = 997184

Showing the first eight; more decompositions exist.
