Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585452, here are decompositions:

5 + 31585447 = 31585452
11 + 31585441 = 31585452
53 + 31585399 = 31585452
83 + 31585369 = 31585452
109 + 31585343 = 31585452
113 + 31585339 = 31585452
139 + 31585313 = 31585452
163 + 31585289 = 31585452

Showing the first eight; more decompositions exist.
