Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474608, here are decompositions:

7 + 31474601 = 31474608
31 + 31474577 = 31474608
37 + 31474571 = 31474608
59 + 31474549 = 31474608
89 + 31474519 = 31474608
107 + 31474501 = 31474608
127 + 31474481 = 31474608
211 + 31474397 = 31474608

Showing the first eight; more decompositions exist.
