Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470054, here are decompositions:

17 + 31470037 = 31470054
41 + 31470013 = 31470054
67 + 31469987 = 31470054
101 + 31469953 = 31470054
131 + 31469923 = 31470054
151 + 31469903 = 31470054
193 + 31469861 = 31470054
197 + 31469857 = 31470054

Showing the first eight; more decompositions exist.
