Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488304, here are decompositions:

5 + 31488299 = 31488304
11 + 31488293 = 31488304
47 + 31488257 = 31488304
101 + 31488203 = 31488304
167 + 31488137 = 31488304
233 + 31488071 = 31488304
251 + 31488053 = 31488304
311 + 31487993 = 31488304

Showing the first eight; more decompositions exist.
