Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523260, here are decompositions:

17 + 31523243 = 31523260
23 + 31523237 = 31523260
29 + 31523231 = 31523260
53 + 31523207 = 31523260
59 + 31523201 = 31523260
149 + 31523111 = 31523260
179 + 31523081 = 31523260
233 + 31523027 = 31523260

Showing the first eight; more decompositions exist.
