Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480896, here are decompositions:

17 + 31480879 = 31480896
23 + 31480873 = 31480896
47 + 31480849 = 31480896
67 + 31480829 = 31480896
103 + 31480793 = 31480896
127 + 31480769 = 31480896
163 + 31480733 = 31480896
257 + 31480639 = 31480896

Showing the first eight; more decompositions exist.
