Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987266, here are decompositions:

67 + 987199 = 987266
73 + 987193 = 987266
139 + 987127 = 987266
199 + 987067 = 987266
223 + 987043 = 987266
277 + 986989 = 987266
283 + 986983 = 987266
307 + 986959 = 987266

Showing the first eight; more decompositions exist.
