Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87286, here are decompositions:

5 + 87281 = 87286
29 + 87257 = 87286
107 + 87179 = 87286
137 + 87149 = 87286
167 + 87119 = 87286
179 + 87107 = 87286
293 + 86993 = 87286
317 + 86969 = 87286

Showing the first eight; more decompositions exist.
