Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471494, here are decompositions:

13 + 31471481 = 31471494
37 + 31471457 = 31471494
83 + 31471411 = 31471494
97 + 31471397 = 31471494
107 + 31471387 = 31471494
137 + 31471357 = 31471494
163 + 31471331 = 31471494
277 + 31471217 = 31471494

Showing the first eight; more decompositions exist.
