Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585004, here are decompositions:

37 + 31584967 = 31585004
43 + 31584961 = 31585004
97 + 31584907 = 31585004
103 + 31584901 = 31585004
151 + 31584853 = 31585004
181 + 31584823 = 31585004
307 + 31584697 = 31585004
337 + 31584667 = 31585004

Showing the first eight; more decompositions exist.
