Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87108, here are decompositions:

5 + 87103 = 87108
37 + 87071 = 87108
59 + 87049 = 87108
67 + 87041 = 87108
71 + 87037 = 87108
97 + 87011 = 87108
127 + 86981 = 87108
139 + 86969 = 87108

Showing the first eight; more decompositions exist.
