Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475064, here are decompositions:

11 + 31475053 = 31475064
67 + 31474997 = 31475064
83 + 31474981 = 31475064
191 + 31474873 = 31475064
197 + 31474867 = 31475064
263 + 31474801 = 31475064
281 + 31474783 = 31475064
317 + 31474747 = 31475064

Showing the first eight; more decompositions exist.
