Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585026, here are decompositions:

7 + 31585019 = 31585026
59 + 31584967 = 31585026
73 + 31584953 = 31585026
79 + 31584947 = 31585026
139 + 31584887 = 31585026
157 + 31584869 = 31585026
173 + 31584853 = 31585026
197 + 31584829 = 31585026

Showing the first eight; more decompositions exist.
