Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523274, here are decompositions:

7 + 31523267 = 31523274
23 + 31523251 = 31523274
31 + 31523243 = 31523274
37 + 31523237 = 31523274
43 + 31523231 = 31523274
47 + 31523227 = 31523274
53 + 31523221 = 31523274
67 + 31523207 = 31523274

Showing the first eight; more decompositions exist.
