Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523424, here are decompositions:

5 + 31523419 = 31523424
13 + 31523411 = 31523424
17 + 31523407 = 31523424
43 + 31523381 = 31523424
131 + 31523293 = 31523424
157 + 31523267 = 31523424
173 + 31523251 = 31523424
181 + 31523243 = 31523424

Showing the first eight; more decompositions exist.
