Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548246, here are decompositions:

97 + 31548149 = 31548246
113 + 31548133 = 31548246
137 + 31548109 = 31548246
167 + 31548079 = 31548246
199 + 31548047 = 31548246
229 + 31548017 = 31548246
239 + 31548007 = 31548246
293 + 31547953 = 31548246

Showing the first eight; more decompositions exist.
