Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470834, here are decompositions:

7 + 31470827 = 31470834
11 + 31470823 = 31470834
41 + 31470793 = 31470834
47 + 31470787 = 31470834
53 + 31470781 = 31470834
113 + 31470721 = 31470834
173 + 31470661 = 31470834
181 + 31470653 = 31470834

Showing the first eight; more decompositions exist.
