Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471348, here are decompositions:

17 + 31471331 = 31471348
59 + 31471289 = 31471348
131 + 31471217 = 31471348
239 + 31471109 = 31471348
257 + 31471091 = 31471348
269 + 31471079 = 31471348
317 + 31471031 = 31471348
347 + 31471001 = 31471348

Showing the first eight; more decompositions exist.
