Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538352, here are decompositions:

19 + 31538333 = 31538352
23 + 31538329 = 31538352
101 + 31538251 = 31538352
113 + 31538239 = 31538352
149 + 31538203 = 31538352
191 + 31538161 = 31538352
199 + 31538153 = 31538352
211 + 31538141 = 31538352

Showing the first eight; more decompositions exist.
