Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523256, here are decompositions:

5 + 31523251 = 31523256
13 + 31523243 = 31523256
19 + 31523237 = 31523256
29 + 31523227 = 31523256
47 + 31523209 = 31523256
113 + 31523143 = 31523256
137 + 31523119 = 31523256
157 + 31523099 = 31523256

Showing the first eight; more decompositions exist.
