Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85716, here are decompositions:

5 + 85711 = 85716
13 + 85703 = 85716
47 + 85669 = 85716
73 + 85643 = 85716
89 + 85627 = 85716
97 + 85619 = 85716
109 + 85607 = 85716
139 + 85577 = 85716

Showing the first eight; more decompositions exist.
