Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997626, here are decompositions:

17 + 997609 = 997626
29 + 997597 = 997626
37 + 997589 = 997626
43 + 997583 = 997626
53 + 997573 = 997626
73 + 997553 = 997626
79 + 997547 = 997626
163 + 997463 = 997626

Showing the first eight; more decompositions exist.
