Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585532, here are decompositions:

3 + 31585529 = 31585532
31 + 31585501 = 31585532
73 + 31585459 = 31585532
79 + 31585453 = 31585532
163 + 31585369 = 31585532
193 + 31585339 = 31585532
271 + 31585261 = 31585532
373 + 31585159 = 31585532

Showing the first eight; more decompositions exist.
