Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608958, here are decompositions:

5 + 31608953 = 31608958
41 + 31608917 = 31608958
47 + 31608911 = 31608958
71 + 31608887 = 31608958
107 + 31608851 = 31608958
137 + 31608821 = 31608958
179 + 31608779 = 31608958
431 + 31608527 = 31608958

Showing the first eight; more decompositions exist.
