Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972640, here are decompositions:

3 + 972637 = 972640
17 + 972623 = 972640
29 + 972611 = 972640
41 + 972599 = 972640
59 + 972581 = 972640
83 + 972557 = 972640
107 + 972533 = 972640
167 + 972473 = 972640

Showing the first eight; more decompositions exist.
