Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532568, here are decompositions:

17 + 31532551 = 31532568
29 + 31532539 = 31532568
47 + 31532521 = 31532568
61 + 31532507 = 31532568
71 + 31532497 = 31532568
79 + 31532489 = 31532568
131 + 31532437 = 31532568
139 + 31532429 = 31532568

Showing the first eight; more decompositions exist.
