Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997632, here are decompositions:

5 + 997627 = 997632
23 + 997609 = 997632
43 + 997589 = 997632
59 + 997573 = 997632
79 + 997553 = 997632
179 + 997453 = 997632
193 + 997439 = 997632
199 + 997433 = 997632

Showing the first eight; more decompositions exist.
