Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978958, here are decompositions:

11 + 978947 = 978958
41 + 978917 = 978958
107 + 978851 = 978958
137 + 978821 = 978958
269 + 978689 = 978958
311 + 978647 = 978958
347 + 978611 = 978958
359 + 978599 = 978958

Showing the first eight; more decompositions exist.
