Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87186, here are decompositions:

5 + 87181 = 87186
7 + 87179 = 87186
37 + 87149 = 87186
53 + 87133 = 87186
67 + 87119 = 87186
79 + 87107 = 87186
83 + 87103 = 87186
103 + 87083 = 87186

Showing the first eight; more decompositions exist.
