Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978892, here are decompositions:

29 + 978863 = 978892
41 + 978851 = 978892
53 + 978839 = 978892
71 + 978821 = 978892
149 + 978743 = 978892
179 + 978713 = 978892
281 + 978611 = 978892
293 + 978599 = 978892

Showing the first eight; more decompositions exist.
