Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986398, here are decompositions:

29 + 986369 = 986398
47 + 986351 = 986398
59 + 986339 = 986398
131 + 986267 = 986398
191 + 986207 = 986398
251 + 986147 = 986398
401 + 985997 = 986398
419 + 985979 = 986398

Showing the first eight; more decompositions exist.
