Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473494, here are decompositions:

7 + 31473487 = 31473494
37 + 31473457 = 31473494
97 + 31473397 = 31473494
163 + 31473331 = 31473494
181 + 31473313 = 31473494
211 + 31473283 = 31473494
277 + 31473217 = 31473494
307 + 31473187 = 31473494

Showing the first eight; more decompositions exist.
