Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997456, here are decompositions:

3 + 997453 = 997456
17 + 997439 = 997456
23 + 997433 = 997456
29 + 997427 = 997456
113 + 997343 = 997456
137 + 997319 = 997456
149 + 997307 = 997456
197 + 997259 = 997456

Showing the first eight; more decompositions exist.
