Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987008, here are decompositions:

19 + 986989 = 987008
67 + 986941 = 987008
79 + 986929 = 987008
151 + 986857 = 987008
157 + 986851 = 987008
229 + 986779 = 987008
241 + 986767 = 987008
271 + 986737 = 987008

Showing the first eight; more decompositions exist.
