Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585038, here are decompositions:

5 + 31585033 = 31585038
19 + 31585019 = 31585038
71 + 31584967 = 31585038
131 + 31584907 = 31585038
137 + 31584901 = 31585038
151 + 31584887 = 31585038
157 + 31584881 = 31585038
229 + 31584809 = 31585038

Showing the first eight; more decompositions exist.
