Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470198, here are decompositions:

5 + 31470193 = 31470198
31 + 31470167 = 31470198
47 + 31470151 = 31470198
101 + 31470097 = 31470198
131 + 31470067 = 31470198
211 + 31469987 = 31470198
337 + 31469861 = 31470198
349 + 31469849 = 31470198

Showing the first eight; more decompositions exist.
