Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514000, here are decompositions:

13 + 31513987 = 31514000
43 + 31513957 = 31514000
73 + 31513927 = 31514000
109 + 31513891 = 31514000
127 + 31513873 = 31514000
151 + 31513849 = 31514000
157 + 31513843 = 31514000
181 + 31513819 = 31514000

Showing the first eight; more decompositions exist.
