Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514178, here are decompositions:

19 + 31514159 = 31514178
29 + 31514149 = 31514178
97 + 31514081 = 31514178
191 + 31513987 = 31514178
211 + 31513967 = 31514178
251 + 31513927 = 31514178
347 + 31513831 = 31514178
359 + 31513819 = 31514178

Showing the first eight; more decompositions exist.
