Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87136, here are decompositions:

3 + 87133 = 87136
17 + 87119 = 87136
29 + 87107 = 87136
53 + 87083 = 87136
167 + 86969 = 87136
197 + 86939 = 87136
293 + 86843 = 87136
353 + 86783 = 87136

Showing the first eight; more decompositions exist.
