Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452198, here are decompositions:

17 + 31452181 = 31452198
61 + 31452137 = 31452198
67 + 31452131 = 31452198
101 + 31452097 = 31452198
109 + 31452089 = 31452198
137 + 31452061 = 31452198
157 + 31452041 = 31452198
179 + 31452019 = 31452198

Showing the first eight; more decompositions exist.
