Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477846, here are decompositions:

5 + 31477841 = 31477846
47 + 31477799 = 31477846
53 + 31477793 = 31477846
149 + 31477697 = 31477846
263 + 31477583 = 31477846
269 + 31477577 = 31477846
293 + 31477553 = 31477846
419 + 31477427 = 31477846

Showing the first eight; more decompositions exist.
