Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475348, here are decompositions:

7 + 31475341 = 31475348
31 + 31475317 = 31475348
61 + 31475287 = 31475348
97 + 31475251 = 31475348
139 + 31475209 = 31475348
241 + 31475107 = 31475348
277 + 31475071 = 31475348
349 + 31474999 = 31475348

Showing the first eight; more decompositions exist.
