Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471468, here are decompositions:

11 + 31471457 = 31471468
29 + 31471439 = 31471468
71 + 31471397 = 31471468
107 + 31471361 = 31471468
137 + 31471331 = 31471468
179 + 31471289 = 31471468
251 + 31471217 = 31471468
359 + 31471109 = 31471468

Showing the first eight; more decompositions exist.
