Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548356, here are decompositions:

13 + 31548343 = 31548356
43 + 31548313 = 31548356
223 + 31548133 = 31548356
277 + 31548079 = 31548356
349 + 31548007 = 31548356
397 + 31547959 = 31548356
439 + 31547917 = 31548356
523 + 31547833 = 31548356

Showing the first eight; more decompositions exist.
