Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972730, here are decompositions:

29 + 972701 = 972730
47 + 972683 = 972730
107 + 972623 = 972730
131 + 972599 = 972730
149 + 972581 = 972730
173 + 972557 = 972730
197 + 972533 = 972730
257 + 972473 = 972730

Showing the first eight; more decompositions exist.
