Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523346, here are decompositions:

17 + 31523329 = 31523346
37 + 31523309 = 31523346
53 + 31523293 = 31523346
67 + 31523279 = 31523346
79 + 31523267 = 31523346
103 + 31523243 = 31523346
109 + 31523237 = 31523346
137 + 31523209 = 31523346

Showing the first eight; more decompositions exist.
