Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997662, here are decompositions:

11 + 997651 = 997662
13 + 997649 = 997662
53 + 997609 = 997662
73 + 997589 = 997662
79 + 997583 = 997662
89 + 997573 = 997662
109 + 997553 = 997662
151 + 997511 = 997662

Showing the first eight; more decompositions exist.
