Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514054, here are decompositions:

31 + 31514023 = 31514054
67 + 31513987 = 31514054
97 + 31513957 = 31514054
127 + 31513927 = 31514054
163 + 31513891 = 31514054
181 + 31513873 = 31514054
211 + 31513843 = 31514054
223 + 31513831 = 31514054

Showing the first eight; more decompositions exist.
