Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468416, here are decompositions:

13 + 31468403 = 31468416
17 + 31468399 = 31468416
19 + 31468397 = 31468416
47 + 31468369 = 31468416
79 + 31468337 = 31468416
97 + 31468319 = 31468416
127 + 31468289 = 31468416
157 + 31468259 = 31468416

Showing the first eight; more decompositions exist.
