Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532682, here are decompositions:

23 + 31532659 = 31532682
29 + 31532653 = 31532682
43 + 31532639 = 31532682
89 + 31532593 = 31532682
101 + 31532581 = 31532682
109 + 31532573 = 31532682
131 + 31532551 = 31532682
193 + 31532489 = 31532682

Showing the first eight; more decompositions exist.
