Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532610, here are decompositions:

13 + 31532597 = 31532610
17 + 31532593 = 31532610
23 + 31532587 = 31532610
29 + 31532581 = 31532610
37 + 31532573 = 31532610
59 + 31532551 = 31532610
71 + 31532539 = 31532610
89 + 31532521 = 31532610

Showing the first eight; more decompositions exist.
