Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87306, here are decompositions:

7 + 87299 = 87306
13 + 87293 = 87306
29 + 87277 = 87306
53 + 87253 = 87306
83 + 87223 = 87306
127 + 87179 = 87306
157 + 87149 = 87306
173 + 87133 = 87306

Showing the first eight; more decompositions exist.
