Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87100, here are decompositions:

17 + 87083 = 87100
29 + 87071 = 87100
59 + 87041 = 87100
89 + 87011 = 87100
107 + 86993 = 87100
131 + 86969 = 87100
149 + 86951 = 87100
173 + 86927 = 87100

Showing the first eight; more decompositions exist.
