Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979938, here are decompositions:

17 + 979921 = 979938
19 + 979919 = 979938
31 + 979907 = 979938
107 + 979831 = 979938
131 + 979807 = 979938
151 + 979787 = 979938
181 + 979757 = 979938
191 + 979747 = 979938

Showing the first eight; more decompositions exist.
