Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468534, here are decompositions:

5 + 31468529 = 31468534
11 + 31468523 = 31468534
17 + 31468517 = 31468534
23 + 31468511 = 31468534
131 + 31468403 = 31468534
137 + 31468397 = 31468534
197 + 31468337 = 31468534
263 + 31468271 = 31468534

Showing the first eight; more decompositions exist.
