Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463346, here are decompositions:

17 + 31463329 = 31463346
29 + 31463317 = 31463346
97 + 31463249 = 31463346
149 + 31463197 = 31463346
179 + 31463167 = 31463346
199 + 31463147 = 31463346
223 + 31463123 = 31463346
263 + 31463083 = 31463346

Showing the first eight; more decompositions exist.
