Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972864, here are decompositions:

17 + 972847 = 972864
31 + 972833 = 972864
37 + 972827 = 972864
41 + 972823 = 972864
71 + 972793 = 972864
163 + 972701 = 972864
181 + 972683 = 972864
227 + 972637 = 972864

Showing the first eight; more decompositions exist.
