Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997516, here are decompositions:

5 + 997511 = 997516
53 + 997463 = 997516
83 + 997433 = 997516
89 + 997427 = 997516
137 + 997379 = 997516
173 + 997343 = 997516
197 + 997319 = 997516
257 + 997259 = 997516

Showing the first eight; more decompositions exist.
