Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474998, here are decompositions:

17 + 31474981 = 31474998
29 + 31474969 = 31474998
67 + 31474931 = 31474998
131 + 31474867 = 31474998
197 + 31474801 = 31474998
251 + 31474747 = 31474998
277 + 31474721 = 31474998
307 + 31474691 = 31474998

Showing the first eight; more decompositions exist.
