Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548008, here are decompositions:

157 + 31547851 = 31548008
277 + 31547731 = 31548008
307 + 31547701 = 31548008
337 + 31547671 = 31548008
367 + 31547641 = 31548008
379 + 31547629 = 31548008
691 + 31547317 = 31548008
727 + 31547281 = 31548008

Showing the first eight; more decompositions exist.
