Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997438, here are decompositions:

5 + 997433 = 997438
11 + 997427 = 997438
47 + 997391 = 997438
59 + 997379 = 997438
131 + 997307 = 997438
179 + 997259 = 997438
191 + 997247 = 997438
317 + 997121 = 997438

Showing the first eight; more decompositions exist.
