Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470958, here are decompositions:

5 + 31470953 = 31470958
17 + 31470941 = 31470958
41 + 31470917 = 31470958
47 + 31470911 = 31470958
89 + 31470869 = 31470958
131 + 31470827 = 31470958
257 + 31470701 = 31470958
317 + 31470641 = 31470958

Showing the first eight; more decompositions exist.
