Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538274, here are decompositions:

13 + 31538261 = 31538274
23 + 31538251 = 31538274
67 + 31538207 = 31538274
71 + 31538203 = 31538274
113 + 31538161 = 31538274
137 + 31538137 = 31538274
167 + 31538107 = 31538274
211 + 31538063 = 31538274

Showing the first eight; more decompositions exist.
