Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532966, here are decompositions:

7 + 31532959 = 31532966
43 + 31532923 = 31532966
67 + 31532899 = 31532966
103 + 31532863 = 31532966
229 + 31532737 = 31532966
307 + 31532659 = 31532966
313 + 31532653 = 31532966
373 + 31532593 = 31532966

Showing the first eight; more decompositions exist.
