Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514198, here are decompositions:

7 + 31514191 = 31514198
97 + 31514101 = 31514198
139 + 31514059 = 31514198
211 + 31513987 = 31514198
241 + 31513957 = 31514198
271 + 31513927 = 31514198
307 + 31513891 = 31514198
349 + 31513849 = 31514198

Showing the first eight; more decompositions exist.
