Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87156, here are decompositions:

5 + 87151 = 87156
7 + 87149 = 87156
23 + 87133 = 87156
37 + 87119 = 87156
53 + 87103 = 87156
73 + 87083 = 87156
107 + 87049 = 87156
163 + 86993 = 87156

Showing the first eight; more decompositions exist.
