Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548956, here are decompositions:

3 + 31548953 = 31548956
139 + 31548817 = 31548956
193 + 31548763 = 31548956
199 + 31548757 = 31548956
223 + 31548733 = 31548956
337 + 31548619 = 31548956
379 + 31548577 = 31548956
409 + 31548547 = 31548956

Showing the first eight; more decompositions exist.
