Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468510, here are decompositions:

11 + 31468499 = 31468510
107 + 31468403 = 31468510
113 + 31468397 = 31468510
173 + 31468337 = 31468510
179 + 31468331 = 31468510
191 + 31468319 = 31468510
239 + 31468271 = 31468510
251 + 31468259 = 31468510

Showing the first eight; more decompositions exist.
