Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548346, here are decompositions:

3 + 31548343 = 31548346
23 + 31548323 = 31548346
47 + 31548299 = 31548346
59 + 31548287 = 31548346
83 + 31548263 = 31548346
197 + 31548149 = 31548346
317 + 31548029 = 31548346
353 + 31547993 = 31548346

Showing the first eight; more decompositions exist.
