Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987966, here are decompositions:

37 + 987929 = 987966
53 + 987913 = 987966
97 + 987869 = 987966
157 + 987809 = 987966
163 + 987803 = 987966
173 + 987793 = 987966
227 + 987739 = 987966
269 + 987697 = 987966

Showing the first eight; more decompositions exist.
