Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470016, here are decompositions:

3 + 31470013 = 31470016
29 + 31469987 = 31470016
113 + 31469903 = 31470016
167 + 31469849 = 31470016
233 + 31469783 = 31470016
293 + 31469723 = 31470016
503 + 31469513 = 31470016
569 + 31469447 = 31470016

Showing the first eight; more decompositions exist.
