Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529022, here are decompositions:

29 + 31528993 = 31529022
53 + 31528969 = 31529022
113 + 31528909 = 31529022
179 + 31528843 = 31529022
181 + 31528841 = 31529022
191 + 31528831 = 31529022
199 + 31528823 = 31529022
211 + 31528811 = 31529022

Showing the first eight; more decompositions exist.
