Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534252, here are decompositions:

5 + 31534247 = 31534252
11 + 31534241 = 31534252
53 + 31534199 = 31534252
83 + 31534169 = 31534252
131 + 31534121 = 31534252
149 + 31534103 = 31534252
173 + 31534079 = 31534252
179 + 31534073 = 31534252

Showing the first eight; more decompositions exist.
