Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475384, here are decompositions:

13 + 31475371 = 31475384
43 + 31475341 = 31475384
67 + 31475317 = 31475384
97 + 31475287 = 31475384
277 + 31475107 = 31475384
313 + 31475071 = 31475384
331 + 31475053 = 31475384
601 + 31474783 = 31475384

Showing the first eight; more decompositions exist.
