Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987152, here are decompositions:

73 + 987079 = 987152
109 + 987043 = 987152
139 + 987013 = 987152
163 + 986989 = 987152
193 + 986959 = 987152
211 + 986941 = 987152
223 + 986929 = 987152
373 + 986779 = 987152

Showing the first eight; more decompositions exist.
