Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87110, here are decompositions:

3 + 87107 = 87110
7 + 87103 = 87110
61 + 87049 = 87110
73 + 87037 = 87110
97 + 87013 = 87110
151 + 86959 = 87110
181 + 86929 = 87110
241 + 86869 = 87110

Showing the first eight; more decompositions exist.
