Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85824, here are decompositions:

5 + 85819 = 85824
7 + 85817 = 85824
31 + 85793 = 85824
43 + 85781 = 85824
73 + 85751 = 85824
107 + 85717 = 85824
113 + 85711 = 85824
157 + 85667 = 85824

Showing the first eight; more decompositions exist.
