Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87200, here are decompositions:

13 + 87187 = 87200
19 + 87181 = 87200
67 + 87133 = 87200
79 + 87121 = 87200
97 + 87103 = 87200
151 + 87049 = 87200
163 + 87037 = 87200
241 + 86959 = 87200

Showing the first eight; more decompositions exist.
