Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523272, here are decompositions:

5 + 31523267 = 31523272
29 + 31523243 = 31523272
41 + 31523231 = 31523272
71 + 31523201 = 31523272
173 + 31523099 = 31523272
191 + 31523081 = 31523272
251 + 31523021 = 31523272
269 + 31523003 = 31523272

Showing the first eight; more decompositions exist.
