Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585192, here are decompositions:

3 + 31585189 = 31585192
11 + 31585181 = 31585192
53 + 31585139 = 31585192
113 + 31585079 = 31585192
131 + 31585061 = 31585192
173 + 31585019 = 31585192
239 + 31584953 = 31585192
311 + 31584881 = 31585192

Showing the first eight; more decompositions exist.
