Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471354, here are decompositions:

23 + 31471331 = 31471354
137 + 31471217 = 31471354
263 + 31471091 = 31471354
311 + 31471043 = 31471354
347 + 31471007 = 31471354
353 + 31471001 = 31471354
401 + 31470953 = 31471354
443 + 31470911 = 31471354

Showing the first eight; more decompositions exist.
