Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595266, here are decompositions:

23 + 31595243 = 31595266
29 + 31595237 = 31595266
47 + 31595219 = 31595266
89 + 31595177 = 31595266
257 + 31595009 = 31595266
347 + 31594919 = 31595266
359 + 31594907 = 31595266
383 + 31594883 = 31595266

Showing the first eight; more decompositions exist.
