Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997506, here are decompositions:

43 + 997463 = 997506
53 + 997453 = 997506
67 + 997439 = 997506
73 + 997433 = 997506
79 + 997427 = 997506
127 + 997379 = 997506
137 + 997369 = 997506
149 + 997357 = 997506

Showing the first eight; more decompositions exist.
