Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997258, here are decompositions:

11 + 997247 = 997258
107 + 997151 = 997258
137 + 997121 = 997258
149 + 997109 = 997258
167 + 997091 = 997258
239 + 997019 = 997258
257 + 997001 = 997258
359 + 996899 = 997258

Showing the first eight; more decompositions exist.
