Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475336, here are decompositions:

19 + 31475317 = 31475336
127 + 31475209 = 31475336
229 + 31475107 = 31475336
283 + 31475053 = 31475336
307 + 31475029 = 31475336
337 + 31474999 = 31475336
367 + 31474969 = 31475336
463 + 31474873 = 31475336

Showing the first eight; more decompositions exist.
