Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471426, here are decompositions:

29 + 31471397 = 31471426
53 + 31471373 = 31471426
137 + 31471289 = 31471426
317 + 31471109 = 31471426
347 + 31471079 = 31471426
383 + 31471043 = 31471426
419 + 31471007 = 31471426
449 + 31470977 = 31471426

Showing the first eight; more decompositions exist.
