Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987876, here are decompositions:

7 + 987869 = 987876
67 + 987809 = 987876
73 + 987803 = 987876
79 + 987797 = 987876
83 + 987793 = 987876
137 + 987739 = 987876
163 + 987713 = 987876
179 + 987697 = 987876

Showing the first eight; more decompositions exist.
