Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482198, here are decompositions:

19 + 31482179 = 31482198
29 + 31482169 = 31482198
31 + 31482167 = 31482198
79 + 31482119 = 31482198
101 + 31482097 = 31482198
109 + 31482089 = 31482198
131 + 31482067 = 31482198
151 + 31482047 = 31482198

Showing the first eight; more decompositions exist.
