Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470056, here are decompositions:

19 + 31470037 = 31470056
43 + 31470013 = 31470056
67 + 31469989 = 31470056
103 + 31469953 = 31470056
199 + 31469857 = 31470056
367 + 31469689 = 31470056
433 + 31469623 = 31470056
487 + 31469569 = 31470056

Showing the first eight; more decompositions exist.
