Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987198, here are decompositions:

5 + 987193 = 987198
7 + 987191 = 987198
71 + 987127 = 987198
97 + 987101 = 987198
101 + 987097 = 987198
109 + 987089 = 987198
131 + 987067 = 987198
137 + 987061 = 987198

Showing the first eight; more decompositions exist.
