Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997470, here are decompositions:

7 + 997463 = 997470
17 + 997453 = 997470
31 + 997439 = 997470
37 + 997433 = 997470
43 + 997427 = 997470
79 + 997391 = 997470
101 + 997369 = 997470
113 + 997357 = 997470

Showing the first eight; more decompositions exist.
