Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595946, here are decompositions:

17 + 31595929 = 31595946
73 + 31595873 = 31595946
79 + 31595867 = 31595946
113 + 31595833 = 31595946
139 + 31595807 = 31595946
163 + 31595783 = 31595946
223 + 31595723 = 31595946
227 + 31595719 = 31595946

Showing the first eight; more decompositions exist.
