Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468610, here are decompositions:

13 + 31468597 = 31468610
37 + 31468573 = 31468610
67 + 31468543 = 31468610
139 + 31468471 = 31468610
157 + 31468453 = 31468610
163 + 31468447 = 31468610
211 + 31468399 = 31468610
241 + 31468369 = 31468610

Showing the first eight; more decompositions exist.
