Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516476, here are decompositions:

7 + 31516469 = 31516476
53 + 31516423 = 31516476
97 + 31516379 = 31516476
149 + 31516327 = 31516476
157 + 31516319 = 31516476
179 + 31516297 = 31516476
223 + 31516253 = 31516476
239 + 31516237 = 31516476

Showing the first eight; more decompositions exist.
