Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514156, here are decompositions:

7 + 31514149 = 31514156
13 + 31514143 = 31514156
43 + 31514113 = 31514156
97 + 31514059 = 31514156
199 + 31513957 = 31514156
229 + 31513927 = 31514156
277 + 31513879 = 31514156
283 + 31513873 = 31514156

Showing the first eight; more decompositions exist.
