Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468518, here are decompositions:

7 + 31468511 = 31468518
19 + 31468499 = 31468518
47 + 31468471 = 31468518
71 + 31468447 = 31468518
127 + 31468391 = 31468518
149 + 31468369 = 31468518
181 + 31468337 = 31468518
199 + 31468319 = 31468518

Showing the first eight; more decompositions exist.
