Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560492, here are decompositions:

23 + 31560469 = 31560492
59 + 31560433 = 31560492
101 + 31560391 = 31560492
109 + 31560383 = 31560492
149 + 31560343 = 31560492
151 + 31560341 = 31560492
193 + 31560299 = 31560492
199 + 31560293 = 31560492

Showing the first eight; more decompositions exist.
