Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523254, here are decompositions:

3 + 31523251 = 31523254
11 + 31523243 = 31523254
17 + 31523237 = 31523254
23 + 31523231 = 31523254
47 + 31523207 = 31523254
53 + 31523201 = 31523254
173 + 31523081 = 31523254
227 + 31523027 = 31523254

Showing the first eight; more decompositions exist.
