Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997730, here are decompositions:

3 + 997727 = 997730
31 + 997699 = 997730
37 + 997693 = 997730
67 + 997663 = 997730
79 + 997651 = 997730
103 + 997627 = 997730
157 + 997573 = 997730
277 + 997453 = 997730

Showing the first eight; more decompositions exist.
