Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471396, here are decompositions:

23 + 31471373 = 31471396
107 + 31471289 = 31471396
179 + 31471217 = 31471396
317 + 31471079 = 31471396
353 + 31471043 = 31471396
389 + 31471007 = 31471396
419 + 31470977 = 31471396
443 + 31470953 = 31471396

Showing the first eight; more decompositions exist.
