Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971666, here are decompositions:

13 + 971653 = 971666
97 + 971569 = 971666
103 + 971563 = 971666
193 + 971473 = 971666
277 + 971389 = 971666
313 + 971353 = 971666
523 + 971143 = 971666
613 + 971053 = 971666

Showing the first eight; more decompositions exist.
