Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468468, here are decompositions:

71 + 31468397 = 31468468
131 + 31468337 = 31468468
137 + 31468331 = 31468468
149 + 31468319 = 31468468
179 + 31468289 = 31468468
197 + 31468271 = 31468468
257 + 31468211 = 31468468
401 + 31468067 = 31468468

Showing the first eight; more decompositions exist.
