Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532952, here are decompositions:

13 + 31532939 = 31532952
29 + 31532923 = 31532952
53 + 31532899 = 31532952
71 + 31532881 = 31532952
79 + 31532873 = 31532952
89 + 31532863 = 31532952
293 + 31532659 = 31532952
313 + 31532639 = 31532952

Showing the first eight; more decompositions exist.
