Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523326, here are decompositions:

17 + 31523309 = 31523326
47 + 31523279 = 31523326
59 + 31523267 = 31523326
83 + 31523243 = 31523326
89 + 31523237 = 31523326
227 + 31523099 = 31523326
347 + 31522979 = 31523326
389 + 31522937 = 31523326

Showing the first eight; more decompositions exist.
