Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468456, here are decompositions:

3 + 31468453 = 31468456
53 + 31468403 = 31468456
59 + 31468397 = 31468456
137 + 31468319 = 31468456
167 + 31468289 = 31468456
197 + 31468259 = 31468456
233 + 31468223 = 31468456
359 + 31468097 = 31468456

Showing the first eight; more decompositions exist.
