Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997396, here are decompositions:

5 + 997391 = 997396
17 + 997379 = 997396
53 + 997343 = 997396
89 + 997307 = 997396
137 + 997259 = 997396
149 + 997247 = 997396
233 + 997163 = 997396
293 + 997103 = 997396

Showing the first eight; more decompositions exist.
