Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987004, here are decompositions:

23 + 986981 = 987004
41 + 986963 = 987004
71 + 986933 = 987004
101 + 986903 = 987004
167 + 986837 = 987004
191 + 986813 = 987004
311 + 986693 = 987004
461 + 986543 = 987004

Showing the first eight; more decompositions exist.
