Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85980, here are decompositions:

47 + 85933 = 85980
71 + 85909 = 85980
127 + 85853 = 85980
137 + 85843 = 85980
149 + 85831 = 85980
151 + 85829 = 85980
163 + 85817 = 85980
199 + 85781 = 85980

Showing the first eight; more decompositions exist.
