Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534216, here are decompositions:

17 + 31534199 = 31534216
29 + 31534187 = 31534216
47 + 31534169 = 31534216
113 + 31534103 = 31534216
137 + 31534079 = 31534216
149 + 31534067 = 31534216
257 + 31533959 = 31534216
293 + 31533923 = 31534216

Showing the first eight; more decompositions exist.
