Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595884, here are decompositions:

3 + 31595881 = 31595884
11 + 31595873 = 31595884
17 + 31595867 = 31595884
53 + 31595831 = 31595884
101 + 31595783 = 31595884
107 + 31595777 = 31595884
113 + 31595771 = 31595884
167 + 31595717 = 31595884

Showing the first eight; more decompositions exist.
