Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997450, here are decompositions:

11 + 997439 = 997450
17 + 997433 = 997450
23 + 997427 = 997450
59 + 997391 = 997450
71 + 997379 = 997450
107 + 997343 = 997450
131 + 997319 = 997450
191 + 997259 = 997450

Showing the first eight; more decompositions exist.
