Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585602, here are decompositions:

5 + 31585597 = 31585602
19 + 31585583 = 31585602
23 + 31585579 = 31585602
31 + 31585571 = 31585602
53 + 31585549 = 31585602
73 + 31585529 = 31585602
101 + 31585501 = 31585602
109 + 31585493 = 31585602

Showing the first eight; more decompositions exist.
