Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987010, here are decompositions:

29 + 986981 = 987010
47 + 986963 = 987010
83 + 986927 = 987010
107 + 986903 = 987010
173 + 986837 = 987010
191 + 986819 = 987010
197 + 986813 = 987010
251 + 986759 = 987010

Showing the first eight; more decompositions exist.
