Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471534, here are decompositions:

11 + 31471523 = 31471534
23 + 31471511 = 31471534
53 + 31471481 = 31471534
137 + 31471397 = 31471534
173 + 31471361 = 31471534
317 + 31471217 = 31471534
443 + 31471091 = 31471534
491 + 31471043 = 31471534

Showing the first eight; more decompositions exist.
