Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986998, here are decompositions:

17 + 986981 = 986998
71 + 986927 = 986998
149 + 986849 = 986998
179 + 986819 = 986998
197 + 986801 = 986998
239 + 986759 = 986998
269 + 986729 = 986998
281 + 986717 = 986998

Showing the first eight; more decompositions exist.
