Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997306, here are decompositions:

47 + 997259 = 997306
59 + 997247 = 997306
197 + 997109 = 997306
263 + 997043 = 997306
269 + 997037 = 997306
293 + 997013 = 997306
353 + 996953 = 997306
419 + 996887 = 997306

Showing the first eight; more decompositions exist.
