Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468522, here are decompositions:

5 + 31468517 = 31468522
11 + 31468511 = 31468522
23 + 31468499 = 31468522
131 + 31468391 = 31468522
191 + 31468331 = 31468522
233 + 31468289 = 31468522
251 + 31468271 = 31468522
263 + 31468259 = 31468522

Showing the first eight; more decompositions exist.
