Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468426, here are decompositions:

23 + 31468403 = 31468426
29 + 31468397 = 31468426
89 + 31468337 = 31468426
107 + 31468319 = 31468426
137 + 31468289 = 31468426
167 + 31468259 = 31468426
179 + 31468247 = 31468426
257 + 31468169 = 31468426

Showing the first eight; more decompositions exist.
