Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971806, here are decompositions:

23 + 971783 = 971806
47 + 971759 = 971806
53 + 971753 = 971806
83 + 971723 = 971806
107 + 971699 = 971806
113 + 971693 = 971806
167 + 971639 = 971806
257 + 971549 = 971806

Showing the first eight; more decompositions exist.
