Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87358, here are decompositions:

41 + 87317 = 87358
59 + 87299 = 87358
101 + 87257 = 87358
107 + 87251 = 87358
137 + 87221 = 87358
179 + 87179 = 87358
239 + 87119 = 87358
251 + 87107 = 87358

Showing the first eight; more decompositions exist.
