Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87310, here are decompositions:

11 + 87299 = 87310
17 + 87293 = 87310
29 + 87281 = 87310
53 + 87257 = 87310
59 + 87251 = 87310
89 + 87221 = 87310
131 + 87179 = 87310
191 + 87119 = 87310

Showing the first eight; more decompositions exist.
