Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997444, here are decompositions:

5 + 997439 = 997444
11 + 997433 = 997444
17 + 997427 = 997444
53 + 997391 = 997444
101 + 997343 = 997444
137 + 997307 = 997444
197 + 997247 = 997444
281 + 997163 = 997444

Showing the first eight; more decompositions exist.
