Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595026, here are decompositions:

5 + 31595021 = 31595026
17 + 31595009 = 31595026
107 + 31594919 = 31595026
149 + 31594877 = 31595026
227 + 31594799 = 31595026
257 + 31594769 = 31595026
269 + 31594757 = 31595026
443 + 31594583 = 31595026

Showing the first eight; more decompositions exist.
