Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532616, here are decompositions:

19 + 31532597 = 31532616
23 + 31532593 = 31532616
29 + 31532587 = 31532616
43 + 31532573 = 31532616
109 + 31532507 = 31532616
127 + 31532489 = 31532616
139 + 31532477 = 31532616
179 + 31532437 = 31532616

Showing the first eight; more decompositions exist.
