Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971532, here are decompositions:

11 + 971521 = 971532
19 + 971513 = 971532
31 + 971501 = 971532
41 + 971491 = 971532
53 + 971479 = 971532
59 + 971473 = 971532
103 + 971429 = 971532
113 + 971419 = 971532

Showing the first eight; more decompositions exist.
