Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523958, here are decompositions:

5 + 31523953 = 31523958
17 + 31523941 = 31523958
19 + 31523939 = 31523958
41 + 31523917 = 31523958
107 + 31523851 = 31523958
157 + 31523801 = 31523958
197 + 31523761 = 31523958
251 + 31523707 = 31523958

Showing the first eight; more decompositions exist.
