Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585214, here are decompositions:

43 + 31585171 = 31585214
181 + 31585033 = 31585214
307 + 31584907 = 31585214
313 + 31584901 = 31585214
457 + 31584757 = 31585214
547 + 31584667 = 31585214
601 + 31584613 = 31585214
607 + 31584607 = 31585214

Showing the first eight; more decompositions exist.
