Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488352, here are decompositions:

23 + 31488329 = 31488352
29 + 31488323 = 31488352
53 + 31488299 = 31488352
59 + 31488293 = 31488352
149 + 31488203 = 31488352
191 + 31488161 = 31488352
251 + 31488101 = 31488352
263 + 31488089 = 31488352

Showing the first eight; more decompositions exist.
