Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978920, here are decompositions:

3 + 978917 = 978920
13 + 978907 = 978920
37 + 978883 = 978920
67 + 978853 = 978920
193 + 978727 = 978920
223 + 978697 = 978920
277 + 978643 = 978920
379 + 978541 = 978920

Showing the first eight; more decompositions exist.
