Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548334, here are decompositions:

3 + 31548331 = 31548334
11 + 31548323 = 31548334
47 + 31548287 = 31548334
53 + 31548281 = 31548334
71 + 31548263 = 31548334
317 + 31548017 = 31548334
353 + 31547981 = 31548334
401 + 31547933 = 31548334

Showing the first eight; more decompositions exist.
