Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87162, here are decompositions:

11 + 87151 = 87162
13 + 87149 = 87162
29 + 87133 = 87162
41 + 87121 = 87162
43 + 87119 = 87162
59 + 87103 = 87162
79 + 87083 = 87162
113 + 87049 = 87162

Showing the first eight; more decompositions exist.
