Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997480, here are decompositions:

17 + 997463 = 997480
41 + 997439 = 997480
47 + 997433 = 997480
53 + 997427 = 997480
89 + 997391 = 997480
101 + 997379 = 997480
137 + 997343 = 997480
173 + 997307 = 997480

Showing the first eight; more decompositions exist.
