Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971580, here are decompositions:

11 + 971569 = 971580
17 + 971563 = 971580
19 + 971561 = 971580
31 + 971549 = 971580
59 + 971521 = 971580
67 + 971513 = 971580
79 + 971501 = 971580
89 + 971491 = 971580

Showing the first eight; more decompositions exist.
