Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972642, here are decompositions:

5 + 972637 = 972642
19 + 972623 = 972642
29 + 972613 = 972642
31 + 972611 = 972642
43 + 972599 = 972642
61 + 972581 = 972642
109 + 972533 = 972642
149 + 972493 = 972642

Showing the first eight; more decompositions exist.
