Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475396, here are decompositions:

3 + 31475393 = 31475396
79 + 31475317 = 31475396
109 + 31475287 = 31475396
307 + 31475089 = 31475396
313 + 31475083 = 31475396
367 + 31475029 = 31475396
397 + 31474999 = 31475396
523 + 31474873 = 31475396

Showing the first eight; more decompositions exist.
