Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468482, here are decompositions:

11 + 31468471 = 31468482
29 + 31468453 = 31468482
79 + 31468403 = 31468482
83 + 31468399 = 31468482
113 + 31468369 = 31468482
151 + 31468331 = 31468482
163 + 31468319 = 31468482
193 + 31468289 = 31468482

Showing the first eight; more decompositions exist.
