Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585614, here are decompositions:

17 + 31585597 = 31585614
31 + 31585583 = 31585614
37 + 31585577 = 31585614
43 + 31585571 = 31585614
97 + 31585517 = 31585614
113 + 31585501 = 31585614
163 + 31585451 = 31585614
167 + 31585447 = 31585614

Showing the first eight; more decompositions exist.
