Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523492, here are decompositions:

19 + 31523473 = 31523492
31 + 31523461 = 31523492
73 + 31523419 = 31523492
163 + 31523329 = 31523492
199 + 31523293 = 31523492
241 + 31523251 = 31523492
271 + 31523221 = 31523492
283 + 31523209 = 31523492

Showing the first eight; more decompositions exist.
