Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87106, here are decompositions:

3 + 87103 = 87106
23 + 87083 = 87106
113 + 86993 = 87106
137 + 86969 = 87106
167 + 86939 = 87106
179 + 86927 = 87106
263 + 86843 = 87106
269 + 86837 = 87106

Showing the first eight; more decompositions exist.
