Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972666, here are decompositions:

5 + 972661 = 972666
17 + 972649 = 972666
29 + 972637 = 972666
43 + 972623 = 972666
53 + 972613 = 972666
67 + 972599 = 972666
89 + 972577 = 972666
109 + 972557 = 972666

Showing the first eight; more decompositions exist.
