Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468408, here are decompositions:

5 + 31468403 = 31468408
11 + 31468397 = 31468408
17 + 31468391 = 31468408
71 + 31468337 = 31468408
89 + 31468319 = 31468408
137 + 31468271 = 31468408
149 + 31468259 = 31468408
197 + 31468211 = 31468408

Showing the first eight; more decompositions exist.
