Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585364, here are decompositions:

3 + 31585361 = 31585364
37 + 31585327 = 31585364
103 + 31585261 = 31585364
193 + 31585171 = 31585364
271 + 31585093 = 31585364
331 + 31585033 = 31585364
397 + 31584967 = 31585364
457 + 31584907 = 31585364

Showing the first eight; more decompositions exist.
