Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997650, here are decompositions:

13 + 997637 = 997650
23 + 997627 = 997650
41 + 997609 = 997650
53 + 997597 = 997650
61 + 997589 = 997650
67 + 997583 = 997650
97 + 997553 = 997650
103 + 997547 = 997650

Showing the first eight; more decompositions exist.
