Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997284, here are decompositions:

5 + 997279 = 997284
11 + 997273 = 997284
17 + 997267 = 997284
37 + 997247 = 997284
83 + 997201 = 997284
131 + 997153 = 997284
137 + 997147 = 997284
163 + 997121 = 997284

Showing the first eight; more decompositions exist.
