Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595914, here are decompositions:

41 + 31595873 = 31595914
47 + 31595867 = 31595914
83 + 31595831 = 31595914
107 + 31595807 = 31595914
131 + 31595783 = 31595914
137 + 31595777 = 31595914
191 + 31595723 = 31595914
197 + 31595717 = 31595914

Showing the first eight; more decompositions exist.
