Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971660, here are decompositions:

7 + 971653 = 971660
97 + 971563 = 971660
139 + 971521 = 971660
181 + 971479 = 971660
241 + 971419 = 971660
271 + 971389 = 971660
307 + 971353 = 971660
379 + 971281 = 971660

Showing the first eight; more decompositions exist.
