Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474950, here are decompositions:

19 + 31474931 = 31474950
83 + 31474867 = 31474950
149 + 31474801 = 31474950
167 + 31474783 = 31474950
173 + 31474777 = 31474950
229 + 31474721 = 31474950
257 + 31474693 = 31474950
263 + 31474687 = 31474950

Showing the first eight; more decompositions exist.
