Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87118, here are decompositions:

11 + 87107 = 87118
47 + 87071 = 87118
107 + 87011 = 87118
137 + 86981 = 87118
149 + 86969 = 87118
167 + 86951 = 87118
179 + 86939 = 87118
191 + 86927 = 87118

Showing the first eight; more decompositions exist.
