Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971538, here are decompositions:

17 + 971521 = 971538
37 + 971501 = 971538
47 + 971491 = 971538
59 + 971479 = 971538
97 + 971441 = 971538
109 + 971429 = 971538
137 + 971401 = 971538
149 + 971389 = 971538

Showing the first eight; more decompositions exist.
