Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585074, here are decompositions:

7 + 31585067 = 31585074
13 + 31585061 = 31585074
41 + 31585033 = 31585074
107 + 31584967 = 31585074
113 + 31584961 = 31585074
127 + 31584947 = 31585074
167 + 31584907 = 31585074
173 + 31584901 = 31585074

Showing the first eight; more decompositions exist.
