Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548252, here are decompositions:

103 + 31548149 = 31548252
149 + 31548103 = 31548252
173 + 31548079 = 31548252
223 + 31548029 = 31548252
271 + 31547981 = 31548252
293 + 31547959 = 31548252
331 + 31547921 = 31548252
401 + 31547851 = 31548252

Showing the first eight; more decompositions exist.
