Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538166, here are decompositions:

5 + 31538161 = 31538166
13 + 31538153 = 31538166
29 + 31538137 = 31538166
53 + 31538113 = 31538166
59 + 31538107 = 31538166
103 + 31538063 = 31538166
113 + 31538053 = 31538166
137 + 31538029 = 31538166

Showing the first eight; more decompositions exist.
