Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87258, here are decompositions:

5 + 87253 = 87258
7 + 87251 = 87258
37 + 87221 = 87258
47 + 87211 = 87258
71 + 87187 = 87258
79 + 87179 = 87258
107 + 87151 = 87258
109 + 87149 = 87258

Showing the first eight; more decompositions exist.
