Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585252, here are decompositions:

53 + 31585199 = 31585252
59 + 31585193 = 31585252
71 + 31585181 = 31585252
113 + 31585139 = 31585252
173 + 31585079 = 31585252
191 + 31585061 = 31585252
233 + 31585019 = 31585252
383 + 31584869 = 31585252

Showing the first eight; more decompositions exist.
