Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467198, here are decompositions:

17 + 31467181 = 31467198
29 + 31467169 = 31467198
31 + 31467167 = 31467198
41 + 31467157 = 31467198
71 + 31467127 = 31467198
109 + 31467089 = 31467198
127 + 31467071 = 31467198
131 + 31467067 = 31467198

Showing the first eight; more decompositions exist.
