Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979988, here are decompositions:

19 + 979969 = 979988
67 + 979921 = 979988
157 + 979831 = 979988
181 + 979807 = 979988
241 + 979747 = 979988
271 + 979717 = 979988
337 + 979651 = 979988
421 + 979567 = 979988

Showing the first eight; more decompositions exist.
