Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85982, here are decompositions:

73 + 85909 = 85982
79 + 85903 = 85982
139 + 85843 = 85982
151 + 85831 = 85982
163 + 85819 = 85982
271 + 85711 = 85982
313 + 85669 = 85982
433 + 85549 = 85982

Showing the first eight; more decompositions exist.
