Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585632, here are decompositions:

19 + 31585613 = 31585632
53 + 31585579 = 31585632
61 + 31585571 = 31585632
83 + 31585549 = 31585632
103 + 31585529 = 31585632
131 + 31585501 = 31585632
139 + 31585493 = 31585632
163 + 31585469 = 31585632

Showing the first eight; more decompositions exist.
