Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595024, here are decompositions:

3 + 31595021 = 31595024
37 + 31594987 = 31595024
61 + 31594963 = 31595024
151 + 31594873 = 31595024
157 + 31594867 = 31595024
163 + 31594861 = 31595024
211 + 31594813 = 31595024
277 + 31594747 = 31595024

Showing the first eight; more decompositions exist.
