Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474884, here are decompositions:

11 + 31474873 = 31474884
17 + 31474867 = 31474884
83 + 31474801 = 31474884
101 + 31474783 = 31474884
107 + 31474777 = 31474884
137 + 31474747 = 31474884
151 + 31474733 = 31474884
163 + 31474721 = 31474884

Showing the first eight; more decompositions exist.
