Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978928, here are decompositions:

11 + 978917 = 978928
89 + 978839 = 978928
107 + 978821 = 978928
131 + 978797 = 978928
179 + 978749 = 978928
239 + 978689 = 978928
281 + 978647 = 978928
311 + 978617 = 978928

Showing the first eight; more decompositions exist.
