Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971728, here are decompositions:

5 + 971723 = 971728
29 + 971699 = 971728
89 + 971639 = 971728
137 + 971591 = 971728
167 + 971561 = 971728
179 + 971549 = 971728
227 + 971501 = 971728
347 + 971381 = 971728

Showing the first eight; more decompositions exist.
