Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87196, here are decompositions:

17 + 87179 = 87196
47 + 87149 = 87196
89 + 87107 = 87196
113 + 87083 = 87196
227 + 86969 = 87196
257 + 86939 = 87196
269 + 86927 = 87196
353 + 86843 = 87196

Showing the first eight; more decompositions exist.
