Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514298, here are decompositions:

7 + 31514291 = 31514298
31 + 31514267 = 31514298
37 + 31514261 = 31514298
59 + 31514239 = 31514298
107 + 31514191 = 31514298
139 + 31514159 = 31514298
149 + 31514149 = 31514298
197 + 31514101 = 31514298

Showing the first eight; more decompositions exist.
