Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546, here are decompositions:

3 + 31543 = 31546
5 + 31541 = 31546
29 + 31517 = 31546
149 + 31397 = 31546
167 + 31379 = 31546
227 + 31319 = 31546
239 + 31307 = 31546
269 + 31277 = 31546

Showing the first eight; more decompositions exist.
