Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595896, here are decompositions:

23 + 31595873 = 31595896
29 + 31595867 = 31595896
89 + 31595807 = 31595896
113 + 31595783 = 31595896
173 + 31595723 = 31595896
179 + 31595717 = 31595896
239 + 31595657 = 31595896
503 + 31595393 = 31595896

Showing the first eight; more decompositions exist.
