Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538252, here are decompositions:

13 + 31538239 = 31538252
139 + 31538113 = 31538252
181 + 31538071 = 31538252
199 + 31538053 = 31538252
223 + 31538029 = 31538252
271 + 31537981 = 31538252
313 + 31537939 = 31538252
331 + 31537921 = 31538252

Showing the first eight; more decompositions exist.
