Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997236, here are decompositions:

17 + 997219 = 997236
29 + 997207 = 997236
73 + 997163 = 997236
83 + 997153 = 997236
89 + 997147 = 997236
113 + 997123 = 997236
127 + 997109 = 997236
137 + 997099 = 997236

Showing the first eight; more decompositions exist.
