Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585334, here are decompositions:

3 + 31585331 = 31585334
7 + 31585327 = 31585334
73 + 31585261 = 31585334
163 + 31585171 = 31585334
241 + 31585093 = 31585334
367 + 31584967 = 31585334
373 + 31584961 = 31585334
433 + 31584901 = 31585334

Showing the first eight; more decompositions exist.
