Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468374, here are decompositions:

5 + 31468369 = 31468374
37 + 31468337 = 31468374
43 + 31468331 = 31468374
103 + 31468271 = 31468374
127 + 31468247 = 31468374
131 + 31468243 = 31468374
151 + 31468223 = 31468374
163 + 31468211 = 31468374

Showing the first eight; more decompositions exist.
