Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986980, here are decompositions:

17 + 986963 = 986980
47 + 986933 = 986980
53 + 986927 = 986980
131 + 986849 = 986980
167 + 986813 = 986980
179 + 986801 = 986980
251 + 986729 = 986980
263 + 986717 = 986980

Showing the first eight; more decompositions exist.
