Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475008, here are decompositions:

11 + 31474997 = 31475008
179 + 31474829 = 31475008
317 + 31474691 = 31475008
431 + 31474577 = 31475008
449 + 31474559 = 31475008
701 + 31474307 = 31475008
947 + 31474061 = 31475008
1031 + 31473977 = 31475008

Showing the first eight; more decompositions exist.
