Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470032, here are decompositions:

19 + 31470013 = 31470032
43 + 31469989 = 31470032
79 + 31469953 = 31470032
109 + 31469923 = 31470032
271 + 31469761 = 31470032
379 + 31469653 = 31470032
409 + 31469623 = 31470032
463 + 31469569 = 31470032

Showing the first eight; more decompositions exist.
