Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585396, here are decompositions:

53 + 31585343 = 31585396
83 + 31585313 = 31585396
107 + 31585289 = 31585396
179 + 31585217 = 31585396
197 + 31585199 = 31585396
257 + 31585139 = 31585396
317 + 31585079 = 31585396
443 + 31584953 = 31585396

Showing the first eight; more decompositions exist.
