Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971790, here are decompositions:

7 + 971783 = 971790
23 + 971767 = 971790
31 + 971759 = 971790
37 + 971753 = 971790
67 + 971723 = 971790
97 + 971693 = 971790
107 + 971683 = 971790
137 + 971653 = 971790

Showing the first eight; more decompositions exist.
