Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997612, here are decompositions:

3 + 997609 = 997612
23 + 997589 = 997612
29 + 997583 = 997612
59 + 997553 = 997612
71 + 997541 = 997612
101 + 997511 = 997612
149 + 997463 = 997612
173 + 997439 = 997612

Showing the first eight; more decompositions exist.
