Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978930, here are decompositions:

13 + 978917 = 978930
23 + 978907 = 978930
47 + 978883 = 978930
59 + 978871 = 978930
67 + 978863 = 978930
79 + 978851 = 978930
109 + 978821 = 978930
131 + 978799 = 978930

Showing the first eight; more decompositions exist.
