Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488496, here are decompositions:

3 + 31488493 = 31488496
89 + 31488407 = 31488496
167 + 31488329 = 31488496
173 + 31488323 = 31488496
197 + 31488299 = 31488496
239 + 31488257 = 31488496
269 + 31488227 = 31488496
293 + 31488203 = 31488496

Showing the first eight; more decompositions exist.
