Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488232, here are decompositions:

5 + 31488227 = 31488232
29 + 31488203 = 31488232
71 + 31488161 = 31488232
131 + 31488101 = 31488232
173 + 31488059 = 31488232
179 + 31488053 = 31488232
239 + 31487993 = 31488232
359 + 31487873 = 31488232

Showing the first eight; more decompositions exist.
