Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85940, here are decompositions:

7 + 85933 = 85940
31 + 85909 = 85940
37 + 85903 = 85940
97 + 85843 = 85940
103 + 85837 = 85940
109 + 85831 = 85940
223 + 85717 = 85940
229 + 85711 = 85940

Showing the first eight; more decompositions exist.
