Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475848, here are decompositions:

71 + 31475777 = 31475848
167 + 31475681 = 31475848
179 + 31475669 = 31475848
251 + 31475597 = 31475848
269 + 31475579 = 31475848
359 + 31475489 = 31475848
389 + 31475459 = 31475848
419 + 31475429 = 31475848

Showing the first eight; more decompositions exist.
