Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548344, here are decompositions:

13 + 31548331 = 31548344
31 + 31548313 = 31548344
43 + 31548301 = 31548344
211 + 31548133 = 31548344
241 + 31548103 = 31548344
313 + 31548031 = 31548344
337 + 31548007 = 31548344
613 + 31547731 = 31548344

Showing the first eight; more decompositions exist.
