Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997328, here are decompositions:

19 + 997309 = 997328
61 + 997267 = 997328
109 + 997219 = 997328
127 + 997201 = 997328
181 + 997147 = 997328
229 + 997099 = 997328
271 + 997057 = 997328
307 + 997021 = 997328

Showing the first eight; more decompositions exist.
