Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986218, here are decompositions:

5 + 986213 = 986218
11 + 986207 = 986218
29 + 986189 = 986218
41 + 986177 = 986218
71 + 986147 = 986218
227 + 985991 = 986218
239 + 985979 = 986218
281 + 985937 = 986218

Showing the first eight; more decompositions exist.
