Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987150, here are decompositions:

7 + 987143 = 987150
23 + 987127 = 987150
53 + 987097 = 987150
61 + 987089 = 987150
67 + 987083 = 987150
71 + 987079 = 987150
83 + 987067 = 987150
89 + 987061 = 987150

Showing the first eight; more decompositions exist.
