Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470666, here are decompositions:

5 + 31470661 = 31470666
13 + 31470653 = 31470666
37 + 31470629 = 31470666
43 + 31470623 = 31470666
47 + 31470619 = 31470666
103 + 31470563 = 31470666
109 + 31470557 = 31470666
197 + 31470469 = 31470666

Showing the first eight; more decompositions exist.
