Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585084, here are decompositions:

5 + 31585079 = 31585084
17 + 31585067 = 31585084
23 + 31585061 = 31585084
131 + 31584953 = 31585084
137 + 31584947 = 31585084
197 + 31584887 = 31585084
431 + 31584653 = 31585084
467 + 31584617 = 31585084

Showing the first eight; more decompositions exist.
