Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471368, here are decompositions:

7 + 31471361 = 31471368
11 + 31471357 = 31471368
37 + 31471331 = 31471368
79 + 31471289 = 31471368
151 + 31471217 = 31471368
197 + 31471171 = 31471368
277 + 31471091 = 31471368
317 + 31471051 = 31471368

Showing the first eight; more decompositions exist.
