Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538344, here are decompositions:

11 + 31538333 = 31538344
17 + 31538327 = 31538344
83 + 31538261 = 31538344
137 + 31538207 = 31538344
191 + 31538153 = 31538344
281 + 31538063 = 31538344
311 + 31538033 = 31538344
347 + 31537997 = 31538344

Showing the first eight; more decompositions exist.
