Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468372, here are decompositions:

3 + 31468369 = 31468372
41 + 31468331 = 31468372
53 + 31468319 = 31468372
83 + 31468289 = 31468372
101 + 31468271 = 31468372
113 + 31468259 = 31468372
149 + 31468223 = 31468372
359 + 31468013 = 31468372

Showing the first eight; more decompositions exist.
