Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997530, here are decompositions:

19 + 997511 = 997530
67 + 997463 = 997530
97 + 997433 = 997530
103 + 997427 = 997530
139 + 997391 = 997530
151 + 997379 = 997530
173 + 997357 = 997530
197 + 997333 = 997530

Showing the first eight; more decompositions exist.
