Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480948, here are decompositions:

29 + 31480919 = 31480948
47 + 31480901 = 31480948
179 + 31480769 = 31480948
419 + 31480529 = 31480948
557 + 31480391 = 31480948
599 + 31480349 = 31480948
659 + 31480289 = 31480948
857 + 31480091 = 31480948

Showing the first eight; more decompositions exist.
