Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87132, here are decompositions:

11 + 87121 = 87132
13 + 87119 = 87132
29 + 87103 = 87132
61 + 87071 = 87132
83 + 87049 = 87132
139 + 86993 = 87132
151 + 86981 = 87132
163 + 86969 = 87132

Showing the first eight; more decompositions exist.
