Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595976, here are decompositions:

7 + 31595969 = 31595976
47 + 31595929 = 31595976
103 + 31595873 = 31595976
107 + 31595869 = 31595976
109 + 31595867 = 31595976
193 + 31595783 = 31595976
199 + 31595777 = 31595976
257 + 31595719 = 31595976

Showing the first eight; more decompositions exist.
