Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595052, here are decompositions:

31 + 31595021 = 31595052
43 + 31595009 = 31595052
53 + 31594999 = 31595052
61 + 31594991 = 31595052
89 + 31594963 = 31595052
149 + 31594903 = 31595052
179 + 31594873 = 31595052
191 + 31594861 = 31595052

Showing the first eight; more decompositions exist.
