Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461298, here are decompositions:

5 + 31461293 = 31461298
17 + 31461281 = 31461298
107 + 31461191 = 31461298
137 + 31461161 = 31461298
149 + 31461149 = 31461298
251 + 31461047 = 31461298
347 + 31460951 = 31461298
419 + 31460879 = 31461298

Showing the first eight; more decompositions exist.
