Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 571686, here are decompositions:

7 + 571679 = 571686
13 + 571673 = 571686
29 + 571657 = 571686
53 + 571633 = 571686
83 + 571603 = 571686
97 + 571589 = 571686
103 + 571583 = 571686
107 + 571579 = 571686

Showing the first eight; more decompositions exist.
