Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599576, here are decompositions:

13 + 31599563 = 31599576
23 + 31599553 = 31599576
89 + 31599487 = 31599576
137 + 31599439 = 31599576
223 + 31599353 = 31599576
227 + 31599349 = 31599576
263 + 31599313 = 31599576
269 + 31599307 = 31599576

Showing the first eight; more decompositions exist.
