Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585324, here are decompositions:

5 + 31585319 = 31585324
11 + 31585313 = 31585324
53 + 31585271 = 31585324
107 + 31585217 = 31585324
131 + 31585193 = 31585324
257 + 31585067 = 31585324
263 + 31585061 = 31585324
443 + 31584881 = 31585324

Showing the first eight; more decompositions exist.
