Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987144, here are decompositions:

17 + 987127 = 987144
43 + 987101 = 987144
47 + 987097 = 987144
61 + 987083 = 987144
83 + 987061 = 987144
101 + 987043 = 987144
131 + 987013 = 987144
163 + 986981 = 987144

Showing the first eight; more decompositions exist.
