Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585006, here are decompositions:

53 + 31584953 = 31585006
59 + 31584947 = 31585006
137 + 31584869 = 31585006
197 + 31584809 = 31585006
293 + 31584713 = 31585006
317 + 31584689 = 31585006
353 + 31584653 = 31585006
389 + 31584617 = 31585006

Showing the first eight; more decompositions exist.
