Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87208, here are decompositions:

29 + 87179 = 87208
59 + 87149 = 87208
89 + 87119 = 87208
101 + 87107 = 87208
137 + 87071 = 87208
167 + 87041 = 87208
197 + 87011 = 87208
227 + 86981 = 87208

Showing the first eight; more decompositions exist.
