Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997286, here are decompositions:

7 + 997279 = 997286
13 + 997273 = 997286
19 + 997267 = 997286
67 + 997219 = 997286
79 + 997207 = 997286
139 + 997147 = 997286
163 + 997123 = 997286
229 + 997057 = 997286

Showing the first eight; more decompositions exist.
