Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87006, here are decompositions:

13 + 86993 = 87006
37 + 86969 = 87006
47 + 86959 = 87006
67 + 86939 = 87006
79 + 86927 = 87006
83 + 86923 = 87006
137 + 86869 = 87006
149 + 86857 = 87006

Showing the first eight; more decompositions exist.
