Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471474, here are decompositions:

5 + 31471469 = 31471474
17 + 31471457 = 31471474
101 + 31471373 = 31471474
113 + 31471361 = 31471474
257 + 31471217 = 31471474
383 + 31471091 = 31471474
431 + 31471043 = 31471474
443 + 31471031 = 31471474

Showing the first eight; more decompositions exist.
