Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532988, here are decompositions:

7 + 31532981 = 31532988
17 + 31532971 = 31532988
29 + 31532959 = 31532988
89 + 31532899 = 31532988
107 + 31532881 = 31532988
211 + 31532777 = 31532988
239 + 31532749 = 31532988
251 + 31532737 = 31532988

Showing the first eight; more decompositions exist.
