Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997630, here are decompositions:

3 + 997627 = 997630
41 + 997589 = 997630
47 + 997583 = 997630
83 + 997547 = 997630
89 + 997541 = 997630
167 + 997463 = 997630
191 + 997439 = 997630
197 + 997433 = 997630

Showing the first eight; more decompositions exist.
