Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532994, here are decompositions:

13 + 31532981 = 31532994
23 + 31532971 = 31532994
71 + 31532923 = 31532994
113 + 31532881 = 31532994
127 + 31532867 = 31532994
131 + 31532863 = 31532994
257 + 31532737 = 31532994
307 + 31532687 = 31532994

Showing the first eight; more decompositions exist.
